----
== Safety & Power Requirements ==
All robots must pass safety inspection prior to fighting.
=== 🔒 Weapon Locks & Safe Handling ===
* '''Mandatory Weapon Locks:''' Any robot with a kinetic/spinning weapon must have a dedicated, brightly colored physical locking device installed whenever the robot is assembled outside of the arena or testing box.
** Standard spring clamps (e.g., [https://www.harborfreight.com/1-34-in-spring-clamp-69291.html Harbor Freight 1-3/4" Spring Clamps]) work well.
* '''Exemptions:''' Non-kinetic weapons (passive wedges and lifters) do not require a weapon lock.
=== ⚡ Radio Failsafe & Power Disconnect ===
* '''Radio Failsafe:''' All active weapon bots must automatically shut off power to drive and spin-down weapons immediately when the transmitter is turned off or signal is lost.
* '''Manual Power Disconnect:''' Robots must have an easily accessible mechanical switch or removable power link capable of fully deactivating the bot in under 15 seconds.
* '''Battery Safety:''' Non-spillable batteries only (LiPo, LiFe, NiMH). Terminals must be insulated against direct shorts.
----
== Match Format & Rules Summary ==
* '''Match Length:''' 2 minutes (or until KO / Tap-Out).
* '''Time Between Matches:''' A competitor may claim a minimum of 20 minutes between their own matches to repair before fighting again.
* '''Load-In / Load-Out:''' Bots load in in a fixed order — robot in weapon-away, power on, weapon lock off, both doors closed, transmitters on, then functionality test. Load-out reverses it: driven to the door, transmitters off, doors open, weapon lock on, robot off. '''Never''' drive a bot or spin a weapon with the doors open. Lifters and wedges may be driven out of the box without a weapon lock.
* '''Knock-Outs (KO):''' A robot unable to demonstrate controlled translational movement for 10 seconds is declared knocked out. An exposed battery is an immediate KO loss.
* '''Pins & Holds:''' Stationary pins are limited to '''5 seconds'''; active pins (moving/sawing) are limited to '''10 seconds''', after which the attacker must fully release.
* '''Un-Sticks:''' Each bot gets one un-stick, but only if the opposing robot did not cause the immobilization. Only the driver of the stuck robot may call it, and the cage manager decides if it applies.
* '''Tap-Out:''' A driver may tap out at any point — by hitting the side of the cage or verbally (loud enough for the cage manager to hear) — to concede the match and protect their robot from further damage.
----
== Judging Criteria ==
''Based on '''Zeke's Judging Criteria V2'''.''

Judging only takes place if neither robot is knocked out (no KO or tap-out before the 2 minutes are up). Robots are scored on damage '''taken''' during the match — the bot with '''fewer points wins'''.

* '''Maximum 8 points:''' 4 points for '''drive''' and 4 points for '''weapon'''.
* '''Partially working = half points.''' A system counts as partially working if it is spinning slowly, working intermittently, or damaged in a way that makes it less effective.
* '''Single systems:''' A single drive or single weapon counts as the whole system and is worth the full 4 points if knocked out entirely.
* '''Dual systems:''' Robots with two weapon systems (e.g., a spinner with a lifter) split the weapon points in half — 2 points per part disabled.

=== Drive Points ===
{| class="wikitable" style="width:100%; text-align:center;"
|-
! Drive !! Fully Working !! Partially Working !! Not Working
|-
| '''Left Drive''' || 0 || 1 || 2
|-
| '''Right Drive''' || 0 || 1 || 2
|-
| '''Both Sides of Drive''' || 0 || 2 || 4
|}

=== Weapon Points ===
{| class="wikitable" style="width:100%; text-align:center;"
|-
! Weapon !! Fully Working !! Partially Working !! Not Working
|-
| '''Part 1''' || 0 || 1 || 2
|-
| '''Part 2''' || 0 || 1 || 2
|-
| '''All Parts''' || 0 || 2 || 4
|}

=== Tiebreaker Rules ===
In the event of a points tie:
# The first robot to lose '''any''' drive functionality loses.
# If it is unclear who lost drive first, the judge may decide based on which robot looked more aggressive and in control.
# If it is still unclear who was winning, the winner is determined by a game of '''Rock, Paper, Scissors'''.

=== 📝 Judging Score Sheet ===
Judges record each robot's '''Robot Name''', '''Drive Damage''', '''Weapon Damage''', and '''Total'''. A printable score sheet is included in the [https://www.wiki-grandrivermakerspace.org/index.php?title=File:Zekes_judging_criteria-1.pdf Judging Criteria V2 PDF].

----
The '''Bambu Lab P1S''' is our everyday workhorse printer — we have '''three''' of them, each with an '''AMS''' (Automatic Material System) for 4-color/multi-material printing. It's a fast, fully enclosed CoreXY machine with automatic bed leveling, vibration compensation, a built-in chamber camera, and an activated carbon filter. It uses the same '''Bambu Studio''' workflow as our [[Bambu_Lab_X1C|X1 Carbon]] and [[Bambu_Lab_H2D|H2D]], so once you've learned one Bambu machine, you've learned them all. Great for PLA, PETG, TPU, and ABS/ASA prints up to 256mm cubed — if your part fits and doesn't need an abrasive or high-temp material, start here.

|}
== Overview ==
The P1S is the enclosed version of Bambu Lab's P1 platform and shares its motion system with the more expensive [[Bambu_Lab_X1C|X1 Carbon]]. The differences from the X1C come down to the extras: the P1S has a simpler button-and-screen interface (no touchscreen), no lidar first-layer scanner, and a standard stainless steel nozzle instead of a hardened one.

The enclosure keeps heat in and drafts out, which is what makes '''ABS and ASA''' print reliably here. It's '''passive''' only — the chamber warms up from the bed (typically 40–50°C), but there's no heater. For materials that need a properly heated chamber, use the [[Bambu_Lab_H2D|H2D]].

'''Printer at a glance:'''
* '''Fast''' — most prints finish in a fraction of the time older printers take.
* '''Hands-off setup''' — auto bed leveling and vibration compensation run on their own before each print.
* '''Multi-color ready''' — the AMS holds 4 spools and switches between them automatically.
* '''Chamber camera''' — check on your print remotely from Bambu Studio or the Bambu Handy app (when the network is up).
== Software ==
=== ⭐ Recommended: Bambu Studio ===
{| class="wikitable" style="width:100%; border: 2px solid #f0a500;"
|-
! style="background:#f0a500; color:white; font-size:115%;" | 🏆 Use Bambu Studio for This Machine
|-
| style="padding:10px;" |
'''Bambu Studio''' is the recommended slicer for the P1S. It ships with tuned P1S profiles for Bambu and common third-party filaments, handles AMS multi-color painting, and exports files ready for the microSD card. Free.
* Select '''"Bambu Lab P1S"''' when adding the printer, with the correct nozzle size (0.4mm unless a volunteer has swapped it).
* Pick the filament profile that matches what's actually loaded — this sets temperatures and speeds.
* Always use the latest stable version.
[https://bambulab.com/en/download/studio Download Bambu Studio →]
|}
'''Also works:''' OrcaSlicer (a popular Bambu Studio offshoot) has full P1S support. Other slicers that export standard G-code can work, but some Bambu features won't.

'''Where to slice:''' Bambu Studio is installed on the makerspace lab PCs — you're welcome to use those, or install it free on your own laptop.

''Tip: The '''weight estimate''' you need for your sticky note and filament payment is shown in Bambu Studio's slice preview, after you click "Slice plate."''
== Startup / First-Print Workflow ==
# Complete mandatory training before use, and sign in on the equipment log.
# Turn on the printer using the power switch on the back.
# Check the build plate: it should be '''clean''', '''seated flat''' on the magnetic bed, and aligned with the pins at the back.
# Check what's loaded in the '''AMS''' — note which color/material is in each slot ('''1–4'''). You'll need to match these in the slicer.
# Slice your model in '''Bambu Studio''' with the P1S profile. In the filament list on the left, set each filament to match the '''AMS slot it's actually in''' (filament 1 = slot 1, etc.).
# Write your '''name, contact info, and estimated filament weight''' on a sticky note and attach it to the printer (see the [[3D_Printing_Area|3D Printing Area]] checklist).
# Send the print to the printer using the '''microSD card''' method below (or over the network, if it's working).
# Let the printer run its automatic calibration (bed leveling, vibration compensation) — '''don't skip this'''. It takes a few minutes before printing starts.
# '''Watch the first layer''' to confirm good bed adhesion.
# Stay reachable during the print; check in periodically on long jobs (or use the chamber camera to check remotely, if the network is up).
# Let the bed cool, then remove the flexible plate and '''flex it''' to pop your print off. Put the plate back, clean up scraps and purge waste. Sign out on the log sheet.

=== 💾 Printing from the microSD Card (Standard Method) ===
{| class="wikitable" style="width:100%;"
|-
| style="background:#fff3cd; border: 2px solid #f0a500; padding:10px;" | ⚠️ '''Always know how to do this.''' The network connection may not be set up or reliable on any given day — the microSD card works every time.
|}
# After slicing in Bambu Studio, click the '''dropdown arrow next to "Print plate"''' (top right) and choose '''"Export plate sliced file."'''
# Save the file (it ends in '''.gcode.3mf''') to the printer's '''microSD card'''. Use a card reader on the lab PC or your laptop if needed.
# Put the card back in the printer's card slot.
# On the printer screen, go to the '''file list''' (SD card), select your file, and start the print.
# If the printer offers calibration options, leave '''bed leveling''' turned on.
''Tip: Give your file a recognizable name (e.g. '''yourname_bracket.gcode.3mf''') so it's easy to find on the screen. Delete old files of yours from the card once your print is done.''

=== 📡 Printing over the Network (When Available) ===
If the printer shows up in Bambu Studio's '''Device''' tab, you can click '''"Print plate"''' to send the job directly. When sending this way, Bambu Studio lets you confirm which AMS slot maps to each filament before the print starts. If the printer doesn't appear or the send fails, '''don't troubleshoot the network''' — just use the microSD card method above.

=== 🎨 Using the AMS (Multi-Color / Multi-Material) ===
Each P1S has an '''AMS''' (Automatic Material System) that holds '''4 spools''' and switches between them automatically during a print.
* '''Match your slots.''' When printing from the microSD card, the printer uses the slot assignments exactly as you set them in Bambu Studio — filament 1 prints from slot 1, and so on. If they don't match what's loaded, you'll get the wrong colors.
* '''Don't swap other people's filament mid-print.''' If you need a different color loaded, only change a slot that isn't being used by a running print, and put it back when you're done.
* '''Color changes create waste.''' Every change purges filament out the back of the printer (the "poop" chute) and may add a prime tower. Use the '''total''' weight Bambu Studio shows after slicing (it includes this waste) for your sticky note and filament payment.
* '''Empty the purge bin''' behind the printer if it's getting full.
* '''Not for the AMS:''' TPU/flexible filament, wet or brittle filament, carbon-fiber or other abrasive filaments, and cardboard spools without an adapter ring. Load those directly into the print head through the external spool path instead — ask a volunteer if unsure.

'''Loading filament into the AMS:''' Open the AMS lid, place the spool on the rollers in an empty slot, and push the filament end into the slot's feeder until it grabs. The AMS reads Bambu RFID spools automatically. For other brands, set the material and color for that slot on the printer screen.
== Materials ==
=== Approved Materials ===
{| class="wikitable" style="width:100%;"
|-
! Material !! Status !! Notes
|-
| '''PLA''' || ✅ || Best all-around choice. Leave the front door or top slightly open for PLA if the chamber gets warm, to prevent heat creep/clogs.
|-
| '''PETG''' || ✅ || Good durability; use glue stick or the textured PEI plate to prevent over-adhesion
|-
| '''TPU''' || ✅ (with care) || Flexible; print slow. Load directly into the print head — '''do not run TPU through the AMS'''
|-
| '''ABS / ASA''' || ✅ || Prints well with the doors closed; enclosure + carbon filter reduce odor. Still use good room ventilation.
|-
| '''PVA''' || ✅ (with care) || Water-soluble support; keep it dry — it absorbs moisture fast
|-
| '''Nylon (PA)''' || ⚠️ Caution || Must be very dry; ask a volunteer first
|-
| style="background:#ffe4e4;" | '''PC (Polycarbonate)''' || style="background:#ffe4e4;" | ❌ Not recommended || style="background:#ffe4e4;" | 300°C nozzle / 100°C bed / unheated chamber are at or below its limits. Use the [[Bambu_Lab_H2D|H2D]].
|-
| style="background:#ffe4e4;" | '''Carbon-fiber / glass-fiber / abrasive filled''' || style="background:#ffe4e4;" | ❌ Not recommended || style="background:#ffe4e4;" | Stainless nozzle — abrasives wear it out quickly. Use the [[Bambu_Lab_H2D|H2D]] (hardened steel nozzle).
|}
''When in doubt about a material/machine combination, ask a volunteer before printing.''
=== Material Handling & Storage ===
* Store spools dry, cool, and out of direct sunlight in a resealable bag with desiccant.
* '''PETG, TPU, Nylon, and PVA absorb moisture''' — wet filament causes stringing, popping, and weak prints. Dry it before use if it's been left out.
* Cardboard spools can shed debris into the AMS — use plastic spools or a spool adapter ring if loading into the AMS.
== Safety ==
'''⚠️ Burns:''' The nozzle reaches 300°C and the bed reaches 100°C. Don't touch either with bare hands. Allow the printer to cool before maintenance.

'''⚠️ Moving parts:''' The print head moves extremely fast. Keep hands out of the printer while it's running — pause or stop the print from the screen first.

'''⚠️ Ventilation:''' The activated carbon filter reduces odors but does '''not''' remove fine particles like a HEPA filter does. Keep the room ventilated, especially for ABS/ASA. Check the SDS for non-Bambu materials.

'''⚠️ Electrical:''' Use the printer's own power cord with an earthed wall socket. Always unplug before maintenance.
{| class="wikitable" style="width:100%;"
|-
! style="background:#fff3cd; border: 2px solid #f0a500;" | ⚠️ Build Plate Warning
|-
| style="background:#fff3cd; border: 2px solid #f0a500; padding:10px;" | Always make sure the flexible build plate is '''seated flat and aligned''' with the pins at the back of the bed before printing. A misaligned plate can cause the nozzle to crash into the bed. Don't use metal scrapers on the PEI surface — flex the plate to release prints instead.
|}
'''General rules:'''
* Complete mandatory training and sign in before use.
* Never leave the first layer unattended.
* Don't store items inside the printer — objects in the chamber can block the print head or bed.
* Don't change printer settings, firmware, or nozzles yourself — ask a volunteer.
* Report jams, failures, and maintenance issues. Clean the bed, remove scraps, and empty the purge bin when done.
== Troubleshooting ==
{| class="wikitable" style="width:100%;"
|-
! Issue !! Likely Cause !! Fix
|-
| '''Poor bed adhesion''' || Oily/dirty plate, wrong plate setting in slicer || Wash the plate with dish soap and water (don't touch the surface with bare fingers); confirm the plate type in Bambu Studio matches the installed plate
|-
| '''Print won't come off''' || PETG over-adhesion, plate still hot || Let the plate cool fully, then flex it. Use glue stick as a release layer for PETG next time
|-

It's official — GRM's first Combat Robotics event is happening as part of '''Grand Rapids Tech Week'''. This is the finish line for our founding season. Whether you're fighting, helping, or just watching, come be part of it.
* '''📅 Date:''' Wednesday, September 16, 2026
* '''🕓 Time:''' 4:00 PM – 8:00 PM
* '''📍 Location:''' Grand River Makerspace, 25 N. Park St, Walker, MI
* '''🤖 Format:''' '''Grudge matches''' — not a bracket. Come as early as you can and fight as many times as you want. See [[#Event_Format_.28Grudge_Matches.29|Event Format]] below.
* '''📄 Attendee Guide:''' [https://www.wiki-grandrivermakerspace.org/index.php?title=File:9-16-2026_GRM_Combat_Robotics_Attendee_Guide-1.pdf 📄 View 9/16 Attendee Guide PDF]

=== 🤺 Competing? RSVP here ===
Fill out the RSVP form so we know you're fighting and can plan the day: '''[https://docs.google.com/forms/d/e/1FAIpQLSeQCS3EQs1pAM38eJz9_rrkmdZMIm9EaIMN22CZnzNdQ8qIpg/viewform?usp=publish-editor 📝 Tournament RSVP Form]'''

This RSVP is in addition to league registration (see [[#League_Overview_.26_Registration|League Overview & Registration]] below) — registration gets you into the league, this RSVP tells us you're fighting on Sept 16.

'''There are no set match times or blocks.''' The event runs as grudge matches, so arrive as early as you can to guarantee you get fights in — the earlier you're through safety and weigh-in, the sooner and more often you can fight.

=== 🙋 Volunteers needed ===
An event this size runs on a few extra hands — none of these roles require technical skill, and volunteers can be competitors' friends/family, members, or anyone who wants in. Mark your interest on the '''[https://docs.google.com/forms/d/e/1FAIpQLSeQCS3EQs1pAM38eJz9_rrkmdZMIm9EaIMN22CZnzNdQ8qIpg/viewform?usp=publish-editor Tournament RSVP Form]''':
* '''Judges''' — watch the fight and help call the close ones (a couple needed).
* '''Weigh-in''' — check bots against the weight table and mark them cleared.
* '''Check-in''' — sign people in and confirm they're registered and paid.
* '''Safety inspection''' — check bots in the test box and mark them safe.
* '''Floater(s)''' — one or two people to fill gaps and lend a hand wherever needed.

=== 👀 Just want to watch? ===
Spectators are very welcome — bring friends! Please RSVP at the Tech Week event page so we get a rough headcount: '''[https://luma.com/techweek-o4cs 🎟️ Spectator RSVP (Tech Week page)]'''

'''⚠️ Minors must be accompanied by a parent or guardian.'''
----
== Event Format (Grudge Matches) ==
This event runs as '''grudge matches''', not a single-elimination bracket. This keeps things flexible for the evening time slot and lets everyone fight as much as they want.

* '''No set arrival time.''' Arrive as early as you can — fights start as soon as two bots are through safety and weigh-in and want to fight (expected around 4:30 PM).
* '''How pairing works:''' Ready robots line up on the open section of the arena table. You're matched with whoever else is ready. To fight someone specific, line your robots up next to each other.
* '''To be "ready":''' Your robot must have passed safety and weigh-in and be placed in line, charged and good to go. If it's your turn and you're not ready, the next bot in line goes.
* '''Fight as often as you want.''' Get back in line as many times as you like for as many fights as you want.
* '''Rumble to finish:''' The night ends with a rumble — as many robots as are still running and want in.

=== ⏱️ Repair time between your fights ===
If your robot needs repairs before it fights again, you can claim it. '''A minimum of 20 minutes will be set aside for a competitor to prepare for another fight if they want it.''' This is optional — if you're ready, you fight; if you want the time, it's yours. It does '''not''' hold up the line: other ready bots keep fighting while you work.

''Example:'' Fighters A and B fight. B needs repairs and wants to fight F later on. Fighters C and D can start their match right after A and B, and B can work on their robot in the meantime — then get back in line when ready.

|}
----
== Safety & Power Requirements ==
All robots must pass safety inspection prior to fighting[cite: 3].
=== 🔒 Weapon Locks & Safe Handling ===
* '''Mandatory Weapon Locks:''' Any robot with a kinetic/spinning weapon must have a dedicated, brightly colored physical locking device installed whenever the robot is assembled outside of the arena or testing box[cite: 3].
** Standard spring clamps (e.g., [https://www.harborfreight.com/1-34-in-spring-clamp-69291.html Harbor Freight 1-3/4" Spring Clamps]) work well.
* '''Exemptions:''' Non-kinetic weapons (passive wedges and lifters) do not require a weapon lock[cite: 3].
=== ⚡ Radio Failsafe & Power Disconnect ===
* '''Radio Failsafe:''' All active weapon bots must automatically shut off power to drive and spin-down weapons immediately when the transmitter is turned off or signal is lost[cite: 3].
* '''Manual Power Disconnect:''' Robots must have an easily accessible mechanical switch or removable power link capable of fully deactivating the bot in under 15 seconds[cite: 3].
* '''Power Indicator:''' Robots must feature a clearly visible LED power light indicating when main battery power is active[cite: 3].
* '''Battery Safety:''' Non-spillable batteries only (LiPo, LiFe, NiMH)[cite: 3]. Terminals must be insulated against direct shorts[cite: 3].
----
== Match Format & Rules Summary ==
* '''Match Length:''' 2 minutes (or until KO / Tap-Out)[cite: 1].
* '''Time Between Matches:''' A competitor may claim a minimum of 20 minutes between their own matches to repair before fighting again. This is optional and competitor-invoked — ready bots are never held back waiting on it (see [[#Repair_time_between_your_fights|Repair time between your fights]]).
* '''Load-In / Load-Out:''' Bots load in in a fixed order — robot in weapon-away, power on, weapon lock off, both doors closed, transmitters on, then functionality test. Load-out reverses it: driven to the door, transmitters off, doors open, weapon lock on, robot off. '''Never''' drive a bot or spin a weapon with the doors open. Lifters and wedges may be driven out of the box without a weapon lock.
* '''Knock-Outs (KO):''' A robot unable to demonstrate controlled translational movement for 10 seconds is declared knocked out[cite: 1]. An exposed battery is an immediate KO loss.
* '''Pins & Holds:''' Stationary pins are limited to '''5 seconds'''; active pins (moving/sawing) are limited to '''10 seconds''', after which the attacker must fully release[cite: 1].
* '''Un-Sticks:''' Each bot gets one un-stick, but only if the opposing robot did not cause the immobilization. Only the driver of the stuck robot may call it, and the cage manager decides if it applies[cite: 1].
* '''Tap-Out:''' A driver may tap out at any point — by hitting the side of the cage or verbally (loud enough for the cage manager to hear) — to concede the match and protect their robot from further damage[cite: 1].
----
== Judging Criteria ==
If a match goes the full 2 minutes without a knockout or tap-out, the winner is decided by the judges using an '''8-point damage scale'''[cite: 1, 2]. Points are awarded for damage '''taken''' — the bot with fewer points wins.
{| class="wikitable" style="width:100%; text-align:center;"
|-
! System !! Fully Functional !! Partially Functional (Half Points) !! Fully Disabled
|-
| '''Drive System (4 Pts Max)''' ''(Left Drive = 2 pts, Right Drive = 2 pts)''[cite: 2] || 0 pts awarded to opponent[cite: 2] || 1 pt awarded to opponent per side[cite: 2] || 2 pts awarded to opponent per side (4 pts for total loss)[cite: 2]
|-
| '''Weapon System (4 Pts Max)''' ''(Single weapon = 4 pts; Dual systems = 2 pts each)''[cite: 2] || 0 pts awarded to opponent[cite: 2] || 1–2 pts awarded to opponent[cite: 2] || 2–4 pts awarded to opponent[cite: 2]
|}
=== Tiebreaker Rules ===
In the event of a points tie:
# The robot that lost drive functionality first loses the tiebreaker[cite: 2].
# If drive loss timing is identical or unclear, the judges will award the win based on aggression and arena control[cite: 2].
# If still completely tied, the winner is determined by a single game of '''Rock, Paper, Scissors'''[cite: 2].

=== 🤺 Competing? RSVP here ===
Fill out the tournament RSVP form so we can pre-plan the bracket and schedule: '''[https://docs.google.com/forms/d/e/1FAIpQLSeQCS3EQs1pAM38eJz9_rrkmdZMIm9EaIMN22CZnzNdQ8qIpg/viewform?usp=publish-editor 📝 Tournament RSVP Form]'''

This RSVP is in addition to league registration (see [[#League_Overview_.26_Registration|League Overview & Registration]] below) — registration gets you into the league, this RSVP tells us you're fighting on Sept 16.

There are two match blocks — pick whichever works for you:

|-
! Block !! Time
|-
| '''Block 1''' || 5:15 – 6:15 PM
|-
| '''Block 2''' || 6:30 – 7:30 PM
|}
Your block sets when your '''first''' match happens. It's single elimination, so if you keep winning you'll fight later rounds and the finals too — the block picks your start time, not your only fight.

=== 🙋 Volunteers needed ===
A tournament this size runs on a few extra hands — none of these roles require technical skill, and volunteers can be competitors' friends/family, members, or anyone who wants in. Mark your interest on the '''[https://docs.google.com/forms/d/e/1FAIpQLSeQCS3EQs1pAM38eJz9_rrkmdZMIm9EaIMN22CZnzNdQ8qIpg/viewform?usp=publish-editor Tournament RSVP Form]''':
* '''Judges''' — watch the fight and help call the close ones (a couple needed).
* '''"On-deck" manager''' — karaoke-style tracking of who's up next and who's on deck.
* '''Check-in''' — sign people in as they arrive.
* '''Floater(s)''' — one or two people to fill gaps and lend a hand wherever needed.

|}

----

== Safety & Power Requirements ==

All robots must pass safety inspection prior to fighting[cite: 3].

=== 🔒 Weapon Locks & Safe Handling ===
* '''Mandatory Weapon Locks:''' Any robot with a kinetic/spinning weapon must have a dedicated, brightly colored physical locking device installed whenever the robot is assembled outside of the arena or testing box[cite: 3].
** Standard spring clamps (e.g., [https://www.harborfreight.com/1-34-in-spring-clamp-69291.html Harbor Freight 1-3/4" Spring Clamps]) work well.
* '''Exemptions:''' Non-kinetic weapons (passive wedges and lifters) do not require a weapon lock[cite: 3].

=== ⚡ Radio Failsafe & Power Disconnect ===
* '''Radio Failsafe:''' All active weapon bots must automatically shut off power to drive and spin-down weapons immediately when the transmitter is turned off or signal is lost[cite: 3].
* '''Manual Power Disconnect:''' Robots must have an easily accessible mechanical switch or removable power link capable of fully deactivating the bot in under 15 seconds[cite: 3].
* '''Power Indicator:''' Robots must feature a clearly visible LED power light indicating when main battery power is active[cite: 3].
* '''Battery Safety:''' Non-spillable batteries only (LiPo, LiFe, NiMH)[cite: 3]. Terminals must be insulated against direct shorts[cite: 3].

----

== Match Format & Rules Summary ==

* '''Match Length:''' 3 minutes (or until KO / Tap-Out)[cite: 1].
* '''Knock-Outs (KO):''' A robot unable to demonstrate controlled translational movement for 10 seconds is declared knocked out[cite: 1].
* '''Pins & Holds:''' Stationary pins are limited to '''5 seconds'''; active pins (moving/sawing) are limited to '''10 seconds''', after which the attacker must fully release[cite: 1].
* '''Un-Sticks:''' One modified un-stick per bot is allowed if bots are tangled or stuck without opponent fault (determined by the referee)[cite: 1].
* '''Tap-Out:''' A driver may verbally tap out at any point to concede the match and protect their robot from further damage[cite: 1].

----

== Judging Criteria ==

If a match goes the full 3 minutes without a knockout or tap-out, the winner is decided by the judges using an '''8-point damage scale'''[cite: 1, 2]:

{| class="wikitable" style="width:100%; text-align:center;"
|-
! System !! Fully Functional !! Partially Functional (Half Points) !! Fully Disabled
|-
| '''Drive System (4 Pts Max)''' ''(Left Drive = 2 pts, Right Drive = 2 pts)''[cite: 2] || 0 pts awarded to opponent[cite: 2] || 1 pt awarded to opponent per side[cite: 2] || 2 pts awarded to opponent per side (4 pts for total loss)[cite: 2]

ComMarker 5W UV Laser

2026-08-14T01:35:34Z

Chris:

= ComMarker Omni X 5W UV Laser =

'''⚠️ NEVER LEAVE THE LASER UNATTENDED WHILE RUNNING ⚠️'''

'''⚠️ KEEP THE GREEN SAFETY DOOR CLOSED WHILE OPERATING ⚠️'''

'''⚠️ USE PORTABLE FUME EXTRACTOR NEAR MACHINE AT ALL TIMES ⚠️'''

The ComMarker Omni X is GRM's UV laser engraver. Unlike CO2 or fiber lasers, the UV laser uses a 355nm wavelength that marks materials through a "cold marking" process — minimal heat means less burning, charring, or warping, making it ideal for plastics, glass, coated metals, and heat-sensitive materials. It does not cut.

This is currently the most beginner-friendly laser at GRM for tumbler engraving with the R5 Rotary attachment.

----

== Software ==

=== ComMarker Studio (Primary) ===

ComMarker Studio is the primary software used for this machine at GRM. It is free to download and use on your own laptop.

[https://commarker.com/download-center#download 📥 Download ComMarker Studio]

'''⚠️ Two required setup steps that trip people up:'''
* '''Don't move any files out of the extracted folder.''' After you unzip the download, leave every file where it is. Moving the .exe out on its own (e.g. to the Desktop) will break it.
* '''You must install two dependencies below''' or the software won't run / won't find the laser. These aren't optional.

'''First-time setup:'''
# Download and extract the ComMarker Studio zip — '''leave all files in the extracted folder; don't move anything out of it'''
# Install the '''Microsoft Visual C++ Redistributable''' (x64) — the software will not run without it. Download the latest supported version here: [https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170 Microsoft Visual C++ Redistributable]
# Run '''CypressDriverInstaller.exe''' (the Cypress USB-Serial driver, included in the extracted folder) — the software will not find the laser over USB without it
# Connect the machine via USB data cable '''before''' opening the software
# Open ComMarker Studio
# On first connection, click '''Confirm''' when prompted to load device parameters, then restart the software
# Click '''Create''' to start a new project

''For Mac users: If you see a security warning that the app cannot be verified, go to System Preferences → Security & Privacy → Open Anyway.''

=== LightBurn (TBD) ===

The Omni X is compatible with LightBurn Pro, but a device profile has not yet been set up at GRM. This is TBD — check with a staff member or volunteer for current status.

If setting up LightBurn manually, the device type is '''BSLFiber'''. Key settings:
* Laser type: '''UV'''
* Enable '''Galvo 2 is X Axis'''
* Door protect port: '''1'''
* Frequency range: 20–200 kHz
* Pulse range: 1–50 ns
* Machine units: mm/sec

See the [[Laser_cutting_and_etching#Software_&_Design|Software & Design section]] of the main laser page for LightBurn download and license information.

=== Other Design Software ===

You can design in any of the following and import into ComMarker Studio or LightBurn:

{| class="wikitable" style="width:100%;"
|-
! Software !! Cost !! Export Formats !! Notes
|-
| '''Inkscape''' || Free || SVG || Native SVG works great
|-
| '''Affinity Designer''' || Free || SVG, PDF, EPS || Professional-grade vector tool
|-
| '''Adobe Illustrator''' || Paid || SVG, EPS, DXF, AI || Industry standard
|-
| '''Any 2D/3D CAD program''' || Varies || DXF, DWG || Export as DXF or DWG for best results
|}

----

== File Formats ==

The UV laser works with '''2D flat files only''' — no 3D formats.

=== Vector Files (preferred) ===
* SVG, DXF, AI, PLT
* Can be scaled to any size without losing quality
* Allows you to assign different operations to different layers

=== Raster/Image Files ===
* BMP, JPG, JPEG, PNG
* Used for photo engraving and image marking
* Works well for high-contrast images on metal and glass surfaces

----

== Machine Overview ==

The Omni X has a distinct design compared to GRM's other lasers — the laser head moves up and down on a column rather than the bed moving. Key components to know:

{| class="wikitable" style="width:100%;"
|-
! Component !! Location !! Notes
|-
| '''Power Switch''' || Front base of machine || Main power on/off
|-
| '''Emergency Stop Switch''' || Front base of machine || Red button — press to immediately cut power; rotate clockwise to reset
|-
| '''Up / Down buttons''' || Front base of machine || Manually raise or lower the laser head for focusing
|-
| '''Indicator Light''' || Under laser head || Must be '''solid green''' before marking — if not green, the laser is not ready
|-
| '''Safety Door (green)''' || Front of machine || Must be closed for the machine to fire; door sensor will prevent operation if open
|-
| '''Auto-focus Sensor''' || Under laser head || Used for automatic focusing — unique to this machine
|-
| '''Field Lens''' || Under laser head || The engraving lens; two positions available (A and B)
|-
| '''Foot Switch''' || Floor, connected by cable || Optional — press to start/stop job hands-free
|}

⚠️ '''If the Emergency Stop has been pressed:''' Resolve the issue first, then rotate the red button clockwise to reset it before powering back on.

----

== Startup Procedure ==

# Ensure the work surface is clean and level
# Turn on the portable fume extractor — position it near the machine
# Press the '''Power Switch''' on the front base to power on
# Verify the '''Emergency Stop''' button is in the released position (rotate clockwise if engaged)
# Connect to your computer via USB data cable
# Open ComMarker Studio — confirm the machine shows as '''Connected'''
# Confirm '''Door Sensor is ON''' in the software status bar
# Verify the '''indicator light under the laser head is solid green''' before running any job

⚠️ '''Operating temperature: 10°C–28°C (50°F–82°F).''' Temperatures outside this range may cause the laser to stop working. Do not use the machine in a cold or very hot environment.

⚠️ '''The portable fume extractor must be running before you start any job.''' A permanent exhaust system is not yet installed.

----

== Focusing the Laser ==

The Omni X has built-in autofocus — this is much simpler than the CO2 laser's manual focus process.

# Place your material on the work surface, aligned under the red sensing spot from the auto-focus sensor
# In ComMarker Studio, click the '''Focus''' button (bottom-right of the UI)
# The machine will automatically adjust the laser head height to the correct focal distance
# Wait for the indicator light to confirm ready status before proceeding

=== Available Lenses ===

The Omni X has two lens positions. The active lens is selected in the software (Field Lens A or B in the status bar).

{| class="wikitable" style="width:100%;"
|-
! Position !! Lens !! Work Area !! Best For !! Notes
|-
| '''A''' (default) || 70mm lens || 70mm x 70mm || High precision; 3D internal glass/crystal engraving; fine detail; photo work || Default lens installed; higher power density
|-
| '''B''' || 150mm lens || 150mm x 150mm || General engraving; everyday flat work; wider coverage || Switch to B-field lens in software after physically swapping
|}

⚠️ '''If you change the lens, you must switch the Field Lens selection in the software to match (A or B).''' The software defaults to Position A (70mm). Running with the wrong setting will produce out-of-focus results.

''See the lens size and power distribution note on the [[Noua_60W_MOPA_Fiber_Laser|Fiber Laser page]] for a general explanation of why larger lenses require adjusted settings.''

----

== Software Settings (ComMarker Studio) ==

=== Key Parameters ===

{| class="wikitable" style="width:100%;"
|-
! Parameter !! What It Does !! UV-Specific Notes
|-
| '''Speed (mm/s)''' || How fast the galvo mirrors scan || Higher speed = lighter mark; lower = darker/deeper
|-
| '''Frequency (kHz)''' || Pulse repetition rate — 20 to 200 kHz || UV range is much narrower than fiber — stay within 20–200 kHz
|-
| '''Pulse Width (ns)''' || Duration of each pulse — 1 to 50 ns || UV pulses are very short — this is what makes "cold marking" possible
|-
| '''Pass''' || Number of repeat passes || Multiple passes at lower power often better than high single-pass power
|-
| '''Interval''' || Spacing between scan lines || 0.1mm is a good all-around starting point
|-
| '''Marking Mode''' || Flat mode (standard) or other modes || Use Flat mode for most work
|}

⚠️ '''UV laser parameters are very different from CO2 and fiber.''' The frequency and pulse width ranges are much narrower. Always run a test first.

=== Framing & Preview ===

Before running any job:
* Click '''Preview''' to visualize the processing area using the preview helper (green card included with machine)
* Place the preview helper on your material, click Preview, confirm placement
* Remove the preview helper and '''close the safety door'''
* Click '''Start (F2)''' to begin

⚠️ '''The safety door must be closed before the laser will fire.'''

----

== Material Test Cards ==

Always run a test on scrap before committing to your final workpiece. UV laser results vary significantly by material type, surface finish, and coating.

Use ComMarker Studio's material library as a starting point (Library button in the Laser Settings panel), then adjust from there based on your test results.

----

== Materials Reference ==

=== ✅ Approved Materials ===

== Safety Rules ==

* '''Keep the green safety door closed while the laser is operating.''' The door sensor will prevent the laser from firing if the door is open — do not bypass or defeat this sensor.
* '''Laser safety glasses are recommended''' even with the enclosed safety door — wear them when the door is open or if working with the door removed.
* '''Always stay by the machine while it's running. Never leave a running job unattended.'''
* '''Run the portable fume extractor''' for every job — position it close to the machine.
* '''Do not operate below 10°C or above 28°C''' — the laser may malfunction outside this temperature range.
* If you need to step away: press '''Stop''' or use the foot switch to pause.
* In an emergency: press the red '''Emergency Stop''' button on the front of the machine.

See [[Laser_cutting_and_etching#Emergency_Procedures|Emergency Procedures]] on the main laser page for emergency contact and equipment locations.

----

== Rotary Engraving ==

The Omni X supports rotary engraving for tumblers and cylindrical objects using the '''ComMarker R5 Multi-Functional Rotary''' attachment. This is currently the most beginner-friendly tumbler engraving option at GRM.

See [[Laser_cutting_and_etching#Accessories|Accessories]] on the main laser page for full rotary attachment details, setup documentation, and video links.

----

== Helpful Features ==

=== Foot Switch ===
The included foot switch connects to the back of the machine and can be used to start/stop jobs hands-free — useful when positioning items for batch work.

=== Batch Processing ===
The galvo scanning system is fast and well-suited for batch marking. Set up a grid of items and use the array/repeat tools in ComMarker Studio to mark them in a single job.

=== Saving Your Settings ===
* Save project files with descriptive names including material and result (e.g., ''pint-glass-logo-2025'')
* Store files in Google Drive or on a flash drive
* Note which lens (A or B) was active when you achieved good results

----
The '''Ultimaker 3 Extended''' is a reliable dual-extrusion FDM printer with a tall build volume and swappable print cores. Its standout feature is dependable dual extrusion with a water-soluble support option (PVA), which lets you print complex geometries with fully dissolvable supports — no breakaway scarring. It's an open-frame machine best suited to PLA, PETG, and support-heavy dual-material prints. Great for functional prototypes, tall parts, and anything needing clean internal cavities or overhangs.

== Overview ==
The Ultimaker 3 Extended uses '''two swappable print cores''' in the print head:
* '''Type AA''' — for build materials (PLA, ABS, Nylon, CPE, etc.) and Ultimaker Breakaway support
* '''Type BB''' — for water-soluble PVA support material
The auto nozzle-lifting system raises the inactive core during printing to prevent oozing and stringing on the part. Because the printer reads NFC-chipped Ultimaker spools, material settings can auto-populate in Ultimaker Cura when connected over the network.
'''Print core sizes:''' The standard cores are 0.4mm. The machine also accepts 0.25mm (fine detail) and 0.8mm (fast/draft) cores — material compatibility differs slightly by core size, so check in Cura before swapping.
== Software ==
=== ⭐ Recommended: Ultimaker Cura ===

|-
! style="background:#f0a500; color:white; font-size:115%;" | 🏆 Use Ultimaker Cura for This Machine
|-
| style="padding:10px;" |
'''Ultimaker Cura''' is the recommended slicer for the Ultimaker 3 Extended. It ships with tuned Ultimaker 3 Extended profiles, handles the dual-extrusion / PVA support workflow, and reads NFC material data when connected over the network. Free.
* Select '''"Ultimaker 3 Extended"''' (not the standard Ultimaker 3) when adding the printer, so the taller build volume is set correctly.
* Requires Cura 2.3 or higher — always use the latest stable version.
[https://ultimaker.com/software/ultimaker-cura Download Ultimaker Cura →]
|}
'''System requirements:''' Windows/macOS/Linux (64-bit), OpenGL 2 graphics, 4GB RAM minimum (8GB+ recommended).
'''Where to slice:''' Cura is installed on the makerspace lab PCs — you're welcome to use those, or install it free on your own laptop. Either way, save the sliced file to a USB flash drive to bring to the printer (see Startup workflow below).
''Tip: When slicing a dual-color or PVA-support print, assign material colors to each model and merge the models before slicing. For support, you can choose which extruder prints the support structure — pick the BB/PVA core for dissolvable supports.''
== Startup / First-Print Workflow ==
# Complete mandatory training before use, and sign in on the equipment log.
# Turn on the printer using the power switch at the back.
# Confirm both print cores are installed (AA in slot 1, BB or second AA in slot 2) and the correct materials are loaded.
# Verify the glass plate is installed, clean, and that the build plate clamps are '''closed''' (open clamps can damage the printer when the bed raises).
# Apply a thin layer of glue stick to the glass plate for adhesion.
# Slice your model in Ultimaker Cura on one of the makerspace lab PCs, or on your own laptop with Cura installed — either way, confirm the print core + material config matches the machine before slicing.
# Save the sliced file to a '''USB flash drive''', then plug it into the printer and select it from the Print menu. (This is our standard process at GRM; the printer also supports sending jobs over Wi-Fi/Ethernet network printing, but USB is what we use here.)
# Watch the first layer to confirm good bed adhesion.
# Stay reachable during the print; check in periodically on long jobs.
# Allow the print and bed to cool before removing. Sign out on the log sheet.
'''Loading materials:''' Load material 2 (rear, e.g. PVA) first, then material 1 (front). Use the material guide for material 1 to prevent the two spools from tangling. Follow the on-screen prompts — the printer heats the core, feeds the filament, and confirms extrusion.

The '''Ultimaker S5''' is our large-format dual-extrusion FDM printer, built for bigger parts and more dependable unattended prints than the [[Ultimaker_3_Extended|Ultimaker 3 Extended]]. It shares the same swappable print core system and water-soluble PVA support workflow as the UM3 Extended, but adds a larger build volume, a hotter bed (up to 140°C), a built-in live camera, a touchscreen interface, and tinted glass front doors that partially enclose the build chamber. It's best suited to PLA, PETG, and support-heavy dual-material prints; without the optional Air Manager filter installed, treat it like an open-frame machine for anything high-fume. Great for large functional prototypes, big assemblies, and clean dual-material prints with dissolvable supports.

== Overview ==
Like the Ultimaker 3 Extended, the S5 uses '''two swappable print cores''' in the print head:
* '''Type AA''' — for build materials (PLA, ABS, Nylon, CPE, etc.) and Ultimaker Breakaway support
* '''Type BB''' — for water-soluble PVA support material
The auto nozzle-lifting system raises the inactive core during printing to prevent oozing and stringing on the part. The printer reads NFC-chipped Ultimaker spools, so material settings can auto-populate in Ultimaker Cura when connected over the network. A '''built-in live camera''' lets you check on a print remotely from Cura or the Ultimaker Digital Factory app without opening the doors.
'''Print core sizes:''' The standard cores are 0.4mm. The machine also accepts 0.25mm (fine detail) and 0.8mm (fast/draft) cores — material compatibility differs slightly by core size, so check in Cura before swapping.
'''Enclosure note:''' The S5's tinted glass front doors help with draft control and heat retention, but the top and back are open on this unit — there is '''no Air Manager filter installed'''. Don't treat this machine as a sealed/filtered enclosure; ventilation rules are the same as for an open-frame printer.

The '''Ultimaker 3 Extended''' is a reliable dual-extrusion FDM printer with a tall build volume and swappable print cores. Its standout feature is dependable dual extrusion with a water-soluble support option (PVA), which lets you print complex geometries with fully dissolvable supports — no breakaway scarring. It's an open-frame machine best suited to PLA, PETG, and support-heavy dual-material prints. Great for functional prototypes, tall parts, and anything needing clean internal cavities or overhangs.

== Overview ==

The Ultimaker 3 Extended uses '''two swappable print cores''' in the print head:
* '''Type AA''' — for build materials (PLA, ABS, Nylon, CPE, etc.) and Ultimaker Breakaway support
* '''Type BB''' — for water-soluble PVA support material

The auto nozzle-lifting system raises the inactive core during printing to prevent oozing and stringing on the part. Because the printer reads NFC-chipped Ultimaker spools, material settings can auto-populate in Ultimaker Cura when connected over the network.

'''Print core sizes:''' The standard cores are 0.4mm. The machine also accepts 0.25mm (fine detail) and 0.8mm (fast/draft) cores — material compatibility differs slightly by core size, so check in Cura before swapping.

== Software ==

=== ⭐ Recommended: Ultimaker Cura ===
{| class="wikitable" style="width:100%; border: 2px solid #f0a500;"
|-
! style="background:#f0a500; color:white; font-size:115%;" | 🏆 Use Ultimaker Cura for This Machine
|-
| style="padding:10px;" |
'''Ultimaker Cura''' is the recommended slicer for the Ultimaker 3 Extended. It ships with tuned Ultimaker 3 Extended profiles, handles the dual-extrusion / PVA support workflow, and reads NFC material data when connected over the network. Free.

* Select '''"Ultimaker 3 Extended"''' (not the standard Ultimaker 3) when adding the printer, so the taller build volume is set correctly.
* Requires Cura 2.3 or higher — always use the latest stable version.

[https://ultimaker.com/software/ultimaker-cura Download Ultimaker Cura →]
|}

'''System requirements:''' Windows/macOS/Linux (64-bit), OpenGL 2 graphics, 4GB RAM minimum (8GB+ recommended).

''Tip: When slicing a dual-color or PVA-support print, assign material colors to each model and merge the models before slicing. For support, you can choose which extruder prints the support structure — pick the BB/PVA core for dissolvable supports.''

== Startup / First-Print Workflow ==

# Complete mandatory training before use, and sign in on the equipment log.
# Turn on the printer using the power switch at the back.
# Confirm both print cores are installed (AA in slot 1, BB or second AA in slot 2) and the correct materials are loaded.
# Verify the glass plate is installed, clean, and that the build plate clamps are '''closed''' (open clamps can damage the printer when the bed raises).
# Apply a thin layer of glue stick to the glass plate for adhesion.
# In Ultimaker Cura, load your model, confirm the print core + material config matches the machine, and slice.
# Send the job via '''network''' (Wi-Fi/Ethernet, using "Print over network") or save G-code to '''USB''' and select it from the Print menu on the printer.
# Watch the first layer to confirm good bed adhesion.
# Stay reachable during the print; check in periodically on long jobs.
# Allow the print and bed to cool before removing. Sign out on the log sheet.

'''Loading materials:''' Load material 2 (rear, e.g. PVA) first, then material 1 (front). Use the material guide for material 1 to prevent the two spools from tangling. Follow the on-screen prompts — the printer heats the core, feeds the filament, and confirms extrusion.

== Materials ==

=== Approved Materials ===
{| class="wikitable" style="width:100%;"
|-
! Material !! Status !! Notes
|-
| '''PLA''' || ✅ || Best all-around choice; use AA core
|-
| '''PETG / CPE''' || ✅ || Good durability; use AA core
|-
| '''PVA''' || ✅ || Water-soluble support only; use BB core
|-
| '''Breakaway''' || ✅ || Mechanical support; use AA core
|-
| '''TPU 95A''' || ✅ (with care) || Flexible; print slow, use AA core
|-
| '''Nylon''' || ⚠️ Caution || Keep dry (hygroscopic); adequate ventilation
|-
| style="background:#ffe4e4;" | '''ABS / ASA''' || style="background:#ffe4e4;" | ⚠️ Ventilation required || style="background:#ffe4e4;" | Officially supported by Ultimaker, but this is an '''open-frame''' machine — styrene fumes are not contained. Use only with strong ventilation, or prefer an enclosed machine. Ask a volunteer first.
|-
| '''PC (Polycarbonate)''' || ⚠️ Caution || High fume; open frame limits results — enclosed machine preferred
|-
| style="background:#ffe4e4;" | '''Carbon-fiber / abrasive filled''' || style="background:#ffe4e4;" | ❌ Not recommended || style="background:#ffe4e4;" | Standard brass nozzle — abrasives wear it out. Use a hardened-nozzle machine.
|}

''When in doubt about a material/machine combination, ask a volunteer before printing.''

=== Material Handling & Storage ===
* Uses '''2.85mm''' filament — '''not''' the common 1.75mm. Do not load 1.75mm filament.
* Store spools dry, cool, and out of direct sunlight in a resealable bag with desiccant.
* '''PVA is highly hygroscopic''' — reseal it with desiccant immediately after printing, or it absorbs moisture, gets sticky, and grinds in the feeder.
* Ultimaker's PRO Series 2.85mm filament (2.88mm true diameter) feeds most reliably through the PTFE tubing.

== Safety ==

'''⚠️ Burns:''' The print head reaches 280°C and the heated bed reaches 100°C. Do not touch either with bare hands. Allow the printer to cool ~30 minutes before maintenance or modifications.

'''⚠️ Moving parts:''' Keep hands out of the reach of the build plate and print head during operation. Control the printer only with the front button or the rear power switch. Allow 5 minutes to cool before reaching inside.

'''⚠️ Ventilation:''' This is an open-frame machine with no fume filtration. Ensure adequate ventilation, especially for any higher-fume material. Non-Ultimaker materials may release VOCs — check the material SDS.

'''⚠️ Electrical:''' Use the supplied Meanwell power supply and cord with an earthed wall socket. Always unplug before maintenance.

{| class="wikitable" style="width:100%;"
|-
! style="background:#fff3cd; border: 2px solid #f0a500;" | ⚠️ Build Plate Clamp Warning
|-
| style="background:#fff3cd; border: 2px solid #f0a500; padding:10px;" | Always keep the build plate clamps '''closed''' when the glass plate is installed. Leaving them open can damage the printer when the build plate raises. Take the glass plate out of the printer when using a spatula, to avoid damaging the clamps.
|}

'''General rules:'''
* Complete mandatory training and sign in before use.
* Never leave the first layer unattended.
* Do not store items inside the printer — objects on the bottom panel prevent proper homing and cause errors.
* Use scrapers and cutters carefully — cut and scrape away from your body.
* Report jams, failures, and maintenance issues. Clean the bed and remove scraps when done.

== Troubleshooting ==
{| class="wikitable" style="width:100%;"
|-
! Issue !! Likely Cause !! Fix
|-
| '''Poor bed adhesion''' || Bed unlevel, no glue, wrong settings || Re-run active leveling, apply thin glue layer, use a default Cura profile
|-
| '''Under-extrusion''' (thin/missing layers, holes) || Feeder tension, Bowden friction, particles, partial clog || Check feeder tension and Bowden tube; clean print core if clogged
|-
| '''Warping''' (corners lift) || Material shrinkage / poor adhesion || Active leveling, glue, correct temps, default Cura profile
|-
| '''Clogged print core''' (no flow 10+ min) || Dirt / carbonized material || Perform hot & cold pull with cleaning filament (or PLA)
|-
| '''Print core not recognized''' || Dirty PCB contacts on core || Clean contact points with a cotton swab and alcohol — do '''not''' touch the chip with bare fingers
|-
| '''PVA grinding in feeder''' || Moisture (most common), coated Bowden tube, clog || Dry/replace PVA, keep humidity below 50%, clean Bowden tube, clean core
|-
| '''Error code on display''' || Various (see manual) || Note the ER## code and go to ultimaker.com/ER## for that specific error

'''⚠️ SAFETY GLASSES REQUIRED WHEN REMOVING SUPPORTS OR POST-PROCESSING ⚠️'''

'''⚠️ NEVER LEAVE THE FIRST LAYER UNATTENDED — CHECK LONG PRINTS PERIODICALLY ⚠️'''

----

----

== 📋 Before You Print — Member Checklist ==

'''A few quick steps every time you start a print — please don't skip these:'''

* '''🏷️ Label your print with a sticky note.''' Write your '''name''' (and a '''phone number and/or email''' if you can) on a sticky note and attach it to the printer you're using. If a print fails or there's an issue, we need to know whose job it is and how to reach you.
* '''⚖️ Write down the filament weight.''' Note the '''weight the slicer estimated''' (in grams) on your sticky note. This is how we track material use for paying for filament — jot it down before you walk away.
* '''👀 Don't hit print and leave.''' '''Stay for the first few layers''' and make sure they're going down cleanly with good bed adhesion. The first layer is where most prints fail — catching a bad start here saves your whole print (and everyone's filament and time).

=== 💵 Paying for Filament ===

Once you know your print's weight, pay for the material you used. There are three easy ways:

* '''Deposit bucket''' — drop your payment in the deposit bucket inside the 3D printing room
* '''Scan the QR code''' — posted in the 3D printing room
* '''Pay online''' — use the links below for the material you printed with

== Safety & Usage ==

=== General Safety Rules ===
* Complete mandatory training before using any printer
* Sign in on the equipment log
* '''Never leave the first layer unattended''' — it's the most common failure point
* Check in on long prints periodically
* Report jams, failures, and maintenance issues
* Clean the bed and remove scraps when you're done

=== Operating Procedures ===
# Complete mandatory training before use
# Sign in on the log sheet
# Load your model in the machine's recommended slicer, using the matching profile
# Verify the correct filament is loaded and the correct plate/surface is installed
# Confirm the bed is clean and (where applicable) adhesion aid is applied
# Start the print and watch the first layer
# Stay reachable during the print; check in periodically on long jobs
# Allow parts to cool before removing from the bed
# Clean the bed and remove supports/scraps
# Sign out on the log sheet

=== FDM Printer Safety ===
* '''Hot surfaces''' — nozzles reach 250°C+ (up to 420°C on the F430) and beds reach 110°C+
* Do not touch the nozzle or heated bed during or immediately after printing
* Do not touch the nozzle or bed during auto-leveling
* Allow parts to cool before removing from the bed
* Use scrapers and cutters carefully — cut and scrape away from your body
* Keep flammable materials away from printers
* Do not reach into a machine while it is running — moving parts can pinch or injure
* Ensure adequate ventilation, especially for ABS/ASA (use enclosed machines only)

=== Fume Safety ===
{| class="wikitable" style="width:100%;"
|-
! Material !! Fume Risk !! Ventilation / Machine Requirement
|-
| PLA || Low || Recommended; any machine
|-
| PETG || Low–Medium || Recommended; any machine
|-
| TPU / Flexible || Low–Medium || Use a direct-drive machine (X1C, Centauri, F430); not the Bowden Kobra Max
|-
| ABS / ASA || High — styrene fumes || '''Enclosed + filtered machine only''' (X1C, Centauri, F430); never on open-frame machines
|-
| Nylon || Medium — may emit irritants || Enclosed machine; keep dry
|-
| PC (Polycarbonate) || High || '''Enclosed, heated-chamber machine only (F430)''' — requires approval
|}

=== Approved Materials by Machine ===

''When in doubt about a material/machine combination, ask a volunteer before printing. Open-frame machines (Kobra Max, Prusa MK2) cannot hold the ambient temperatures ABS/ASA need and should not run them.''

=== Prohibited / Restricted Practices ===
{| class="wikitable" style="width:100%;"
|-
! Practice !! Reason
|-
| style="background:#ffe4e4;" | '''Running ABS/ASA on open-frame machines''' || style="background:#ffe4e4;" | '''Warping/cracking and unfiltered styrene fumes — enclosed machines only'''
|-
| '''Running TPU/flexible through the Kobra Max''' || Bowden tube causes flexibles to buckle and jam — use a direct-drive machine
|-
| '''Abrasive (CF/GF) filament in a non-hardened nozzle''' || Wears out brass nozzles quickly — hardened-nozzle machines only
|-
| '''Leaving the first layer unattended''' || Most failures happen in the first layer — stay present
|-
| '''Printing unknown/unlabeled filament''' || Unknown melt temps and fumes — verify material before printing
|}

=== Material Storage ===
* Keep filament dry — store hygroscopic materials (Nylon, TPU, PETG) in sealed containers with desiccant or in the dry box
* Label spools clearly with material type
* Return shared filament and tools to their storage location when done

=== Waste Disposal ===
* Failed PLA prints and supports — regular trash
* Failed ABS/PETG/other prints — check local recycling options
* Keep scraps off the floor and out of machine rails

=== Emergency Procedures ===
* '''Fire extinguisher location:''' ''[TO BE FILLED IN]''
* '''First aid kit:''' Near the bathroom inside the main makerspace room

== Safety & Usage ==

=== General Safety Rules ===
* Complete mandatory training before using any printer
* Sign in on the equipment log
* '''Never leave the first layer unattended''' — it's the most common failure point
* Check in on long prints periodically
* Report jams, failures, and maintenance issues
* Clean the bed and remove scraps when you're done

=== Operating Procedures ===
# Complete mandatory training before use
# Sign in on the log sheet
# Load your model in the machine's recommended slicer, using the matching profile
# Verify the correct filament is loaded and the correct plate/surface is installed
# Confirm the bed is clean and (where applicable) adhesion aid is applied
# Start the print and watch the first layer
# Stay reachable during the print; check in periodically on long jobs
# Allow parts to cool before removing from the bed
# Clean the bed and remove supports/scraps
# Sign out on the log sheet

=== FDM Printer Safety ===
* '''Hot surfaces''' — nozzles reach 250°C+ (up to 420°C on the F430) and beds reach 110°C+
* Do not touch the nozzle or heated bed during or immediately after printing
* Do not touch the nozzle or bed during auto-leveling
* Allow parts to cool before removing from the bed
* Use scrapers and cutters carefully — cut and scrape away from your body
* Keep flammable materials away from printers
* Do not reach into a machine while it is running — moving parts can pinch or injure
* Ensure adequate ventilation, especially for ABS/ASA (use enclosed machines only)
