== Bits & Tooling ==
== Connecting to Universal G-Code Sender (UGS) ==
 
# Open UGS on the CNC laptop (go to ugsplatform → bin → ugsplatform). ''Mac users: select the version without the yellow square icon. Java must be installed — download from java.com if needed.''
# Plug the USB cable from the machine's electronics box into the laptop
# In UGS, click the '''circular arrows (refresh) icon''' next to the Port dropdown to detect the correct COM port — it will usually find it automatically
# Click the '''plug icon''' to connect — it should turn '''orange''' and machine settings will scroll across the console. If nothing appears, disconnect and try a different COM port.
# Confirm the Controller State shows '''Idle''' (not Alarm) before proceeding


Choosing the right bit is one of the most important parts of CNC routing. Using the wrong bit for a material or operation will produce poor results and can break the bit.
=== UGS Jog Controller Settings ===


=== Common Bit Types ===
Before jogging, set these values in the Jog Controller panel so movement is visible:

|-
| '''Upcut Spiral (End Mill)''' || General cutting, profiling, pocketing in wood and plastic || Pulls chips up and out of the cut; leaves a clean bottom edge; most common bit for general work
|-
| '''Downcut Spiral''' || Top surface finish on wood and plywood || Pushes chips down; cleaner top edge; can pack chips into cut — not ideal for deep pockets
|-
| '''Compression Bit''' || Plywood and sheet goods || Combines upcut and downcut; clean top and bottom edges; best for finished plywood panels

=== Bit Shank Sizes ===
The DeWalt DW618 uses a standard router collet. Check which collet is installed before selecting bits:
* '''1/4" shank''' — most common; fits the standard collet
* '''1/2" shank''' — larger bits; requires collet swap
Ask a staff member or volunteer if you're unsure which collet is currently installed.

== Setting Work Zero (X, Y, Z Origin) ==
== Setting Work Zero (X, Y, Z Origin) ==


Work zero tells the machine where your job starts. This is separate from the machine's home position.
Your CAD/CAM software will define the project origin — make sure your machine zero matches where your file expects it to be. Check the UGS visualizer to confirm.


* '''X and Y zero''' — typically set to a corner of your material (usually front-left) or the center, depending on how your file was set up in VCarve
=== X and Y Zero ===
* '''Z zero''' — the top surface of your material. Use the Z-probe touch plate if available, or manually jog down until the bit just touches the surface, then zero Z
Jog the machine to the correct starting corner or center of your material (matching what you set in VCarve). In the Common Actions panel, click '''Reset Work Coordinates''' to zero X and Y.


''Always confirm your work zero setup matches how your file was set up in VCarve before running.''
=== Z Zero (Paper Method) ===
# Jog the bit over your material
# Reduce step size to a small value (0.1mm or less) to avoid crashing into the stock
# Slowly jog Z down until the bit just '''pinches a piece of paper''' between the bit and the material surface
# In the UGS console, type one of the following and press Enter:
#* '''Inches mode:''' <code>g92 x0 y0 z0.004</code>
#* '''MM mode:''' <code>g92 x0 y0 z0.01</code>
# This sets X and Y to zero and accounts for the paper thickness on Z
# Jog Z up to a safe height — you are ready to run your program
 
''Tip: The UGS visualizer shows where your job origin is set. A crosshair at lower-left means origin is front-left of stock; a crosshair at center means origin is center of stock. Make sure this matches your VCarve setup.''

== Clearing an Alarm ==
 
If UGS shows a red '''ALARM''' state:
 
# In the '''Common Actions''' panel, click '''Turn Off Alarm Lock'''
# If the alarm was caused by the machine hitting a homing switch, you will also need to '''jog off the switch''' after clearing the alarm — may need to be done twice depending on your step size
# Once clear, re-home the machine before running any job

== Feed Rate & Depth of Cut ==
== Feed Rate & Depth of Cut ==


These two settings control how aggressively the machine cuts. Getting them wrong is the most common cause of broken bits and poor results.
'''General starting points for 1/4" upcut spiral bit:'''
 
* '''Feed rate''' — how fast the bit moves through the material (mm/min or in/min)
* '''Depth of cut (DOC)''' — how deep the bit cuts per pass
* '''Step over''' — for pocketing, how much of the bit diameter overlaps each pass (typically 40–50%)

⚠️ '''When in doubt, go slower and shallower.''' You can always increase speed. A broken bit wastes time and money. Multiple passes at a conservative depth are almost always better than one aggressive pass.

=== Always Run a Test / Air Cut First ===
=== Always Air Cut First ===
Before cutting your actual material, raise Z by 10–20mm and run the job in the air — watch the toolpath trace out and confirm it matches your expectations. This catches origin errors before they cost you material.

MillRight Mega V CNC Router

⚠️ NEVER LEAVE THE CNC UNATTENDED WHILE RUNNING ⚠️

⚠️ EYE PROTECTION REQUIRED WHEN MACHINE IS OPERATING ⚠️

⚠️ DUST COLLECTION MUST BE RUNNING BEFORE STARTING ANY JOB ⚠️

The MillRight Mega V is GRM's CNC router — a computer-controlled cutting and carving machine that uses a spinning router bit to remove material. It can cut, carve, pocket, profile, engrave, and create 3D relief work in wood, plastics, aluminum, and more. This page covers software, setup, settings, safety, and tips to help you get great results.

📄 Introduction to CNC Routing with the MillRight XL V2 — GRM's own getting started guide for this machine.

Understanding CNC vs. Laser

If you're coming from the laser cutters, CNC routing works differently in a few important ways:

  • The laser removes material with light — the CNC removes material physically with a spinning bit
  • CNC produces chips and dust — dust collection is mandatory, not optional
  • Tool selection matters — different bits are used for different materials and operations (unlike lasers which use the same beam for everything)
  • Feed rate and depth of cut interact — too aggressive and you'll break bits or damage the machine
  • Jobs take longer to set up but the machine can do things lasers can't — true 3D carving, joinery, cutting thick stock, aluminum machining

Software

CNC routing requires two types of software: a CAD/CAM program to design your part and generate toolpaths, and a sender program to stream the G-code to the machine.

CAD/CAM Software

Software Cost Best For Notes
VCarve Pro (Makerspace Edition) Included with GRM membership 2D cutting, profiling, pocketing, V-carving, sign making Primary recommended software at GRM; installed on the CNC laptop; see VCarve section below for important notes on how the Makerspace Edition works

Sender Software

Software Cost Notes
Universal G-Code Sender (UGS) Free Primary sender used at GRM; runs on the laptop connected to the machine; universalgcodesender.com — download from the MillRight Resources page
MillMage See above Includes built-in machine control — no separate sender needed if using MillMage end-to-end

VCarve Pro — Makerspace Edition

📄 VCarve Pro Makerspace Edition Instructions

VCarve Pro Makerspace Edition works slightly differently than a standard VCarve license:

  • The full software is installed on the GRM CNC laptop — you can design and cut here
  • At home, download the free VCarve trial to design your files — save as a VCarve project (.crv)
  • Bring your .crv file to GRM on a USB drive, open it on the GRM laptop to generate toolpaths and cut
  • You cannot generate toolpaths or save G-code from the trial version at home — only at the GRM machine

Post Processor (critical): When saving toolpaths in VCarve, you must select the correct post processor:

  • Standard cutting: Grbl (mm) or Grbl (inch)
  • 4th axis rotary work: G-Code WrapY2A (mm) or G-Code WrapY2A (inch)

In VCarve v11+, go to Toolpath commands (arrow at top left) → Save Toolpath → select the correct post processor from the dropdown.

Fusion 360 Post Processor

In Fusion 360, go to Actions → Post Process and select the Grbl / grbl post processor, then click Post. Do not use any other post processor — it will produce G-code the machine cannot read.

Fusion 360 Documentation | Fusion 360 YouTube

File Formats

Format Use Notes
SVG 2D vector design Import into VCarve or MillMage for toolpath generation
DXF / DWG 2D vector (CAD) Good for precise technical drawings; imports cleanly into VCarve
STL 3D model Used for 3D relief carving in VCarve Pro or Fusion 360
.crv VCarve project file Native VCarve format; bring this to GRM to open on the CNC laptop
.nc / .gcode G-code (toolpath output) Generated by CAM software; sent to machine via UGS or MillMage

Connecting to Universal G-Code Sender (UGS)

  1. Open UGS on the CNC laptop (go to ugsplatform → bin → ugsplatform). Mac users: select the version without the yellow square icon. Java must be installed — download from java.com if needed.
  2. Plug the USB cable from the machine's electronics box into the laptop
  3. In UGS, click the circular arrows (refresh) icon next to the Port dropdown to detect the correct COM port — it will usually find it automatically
  4. Click the plug icon to connect — it should turn orange and machine settings will scroll across the console. If nothing appears, disconnect and try a different COM port.
  5. Confirm the Controller State shows Idle (not Alarm) before proceeding

UGS Jog Controller Settings

Before jogging, set these values in the Jog Controller panel so movement is visible:

Setting Recommended Value (mm) Recommended Value (inches)
Step size XY 10 mm 0.394"
Step size Z 4 mm 0.157"
Feed rate 9,000 mm/min 354 in/min

Startup Procedure

  1. Connect the CNC laptop to the machine via USB cable
  2. Power on the machine controller (switch on the electronics enclosure)
  3. Open UGS on the laptop and connect (see above)
  4. Home the machine — click Home Machine in the Common Actions panel, or type $H in the console and press Enter. The machine will move to find all three axis home switches.
  5. Secure your material to the bed using clamps, tape, or the spoilboard hold-down system
  6. Set your Work Zero (X, Y, Z) — see zeroing section below

⚠️ Always home the machine at the start of every session. Without homing, the machine has no reference for where it is and jobs will not run in the correct location.

Setting Work Zero (X, Y, Z Origin)

Your CAD/CAM software will define the project origin — make sure your machine zero matches where your file expects it to be. Check the UGS visualizer to confirm.

X and Y Zero

Jog the machine to the correct starting corner or center of your material (matching what you set in VCarve). In the Common Actions panel, click Reset Work Coordinates to zero X and Y.

Z Zero (Paper Method)

  1. Jog the bit over your material
  2. Reduce step size to a small value (0.1mm or less) to avoid crashing into the stock
  3. Slowly jog Z down until the bit just pinches a piece of paper between the bit and the material surface
  4. In the UGS console, type one of the following and press Enter:
    • Inches mode: g92 x0 y0 z0.004
    • MM mode: g92 x0 y0 z0.01
  5. This sets X and Y to zero and accounts for the paper thickness on Z
  6. Jog Z up to a safe height — you are ready to run your program

Tip: The UGS visualizer shows where your job origin is set. A crosshair at lower-left means origin is front-left of stock; a crosshair at center means origin is center of stock. Make sure this matches your VCarve setup.

Clearing an Alarm

If UGS shows a red ALARM state:

  1. In the Common Actions panel, click Turn Off Alarm Lock
  2. If the alarm was caused by the machine hitting a homing switch, you will also need to jog off the switch after clearing the alarm — may need to be done twice depending on your step size
  3. Once clear, re-home the machine before running any job

Running a Job

  1. Load your G-code file in UGS: File → Open (or click the folder icon)
  2. Check the visualizer — confirm the toolpath looks correct and the origin is in the right location
  3. Turn on the DeWalt DW618 router — set the speed dial for your material (see table below)
  4. Turn on dust collection
  5. Click Start/Resume G-Code in the Common Actions panel
  6. Stay by the machine — watch the first few passes carefully. If anything looks wrong, click Pause G-Code File or Soft Reset immediately.

DeWalt DW618 Speed Settings

Dial Setting RPM (approx.) Best For
1 ~8,000 RPM Aluminum, soft metals (single flute bit)
2 ~10,000 RPM Hardwoods, dense materials
3–4 ~12,000–16,000 RPM General wood routing, plywood, MDF
5–6 ~18,000–24,000 RPM Plastics, light engraving, V-carving

Bits & Tooling

Common Bit Types

Bit Type Best For Notes
Upcut Spiral (End Mill) General cutting, profiling, pocketing in wood and plastic Pulls chips up and out; clean bottom edge; most common for general work
Downcut Spiral Clean top surface finish on plywood Pushes chips down; can pack into deep pockets
Compression Bit Finished plywood and sheet goods Clean top and bottom edges; best for cabinet/panel work
V-Bit (60°, 90°) V-carving, lettering, decorative engraving Used with VCarve's V-carving toolpath
Ball Nose 3D relief carving, curved surfaces Used for finishing passes on 3D work
Straight Flute Plastics, acrylic Reduces heat buildup; prevents melting
Single Flute Aluminum, soft metals Clears chips efficiently; slower feed rates required

Bit Shank Sizes

The DeWalt DW618 uses a standard router collet:

  • 1/4" shank — most common; fits the standard collet
  • 1/2" shank — larger bits; requires collet swap — ask a staff member

Feed Rate & Depth of Cut

General starting points for 1/4" upcut spiral bit:

Material Feed Rate Depth Per Pass Router Speed
Softwood (pine, cedar) 1500–2500 mm/min 4–6mm Dial 3–4
Hardwood (oak, maple) 1000–2000 mm/min 3–4mm Dial 3–4
Plywood (birch, cabinet) 1500–2500 mm/min 4–6mm Dial 3–4
MDF 2000–3000 mm/min 4–6mm Dial 3–4
Acrylic / Plastics 1000–2000 mm/min 1–2mm Dial 5–6
Aluminum (6061) 500–1000 mm/min 0.5–1mm Dial 1–2

⚠️ When in doubt, go slower and shallower. Multiple passes at conservative depth are almost always better than one aggressive pass.

Workholding

  • Clamps — most common; ensure clamps don't interfere with the toolpath
  • Double-sided tape — good for thin stock or when clamps would be in the way; use carpet tape or machinist tape
  • Screws into spoilboard — for larger sheet goods; screw through sacrificial areas into the spoilboard
  • Tabs — add small holding tabs in VCarve to keep cut pieces attached until the job finishes; snap or cut off afterward

Always confirm clamps and fasteners are clear of the toolpath in the UGS visualizer before running.

Spoilboard

The spoilboard is the sacrificial MDF surface the machine cuts into. It protects the machine bed and allows cutting all the way through material.

  • Cutting into the spoilboard is normal and expected
  • The spoilboard needs to be surfaced (flattened) periodically — ask a staff member if it looks uneven or heavily damaged
  • Do not cut into the aluminum bed beneath the spoilboard

Materials Reference

✅ Approved Materials

Material Cut Carve/Engrave Notes
Softwood (pine, cedar, poplar) Yes Yes Easy to machine; watch for tearout with wrong bit direction
Hardwood (oak, maple, walnut) Yes Yes Slower feed rates; sharp bits essential
Plywood (birch, cabinet grade) Yes Yes Use compression or downcut bit for clean edges
MDF Yes Yes Heavy dust — dust collection essential; dulls bits faster than solid wood
Acrylic (cast) Yes Yes Single or straight flute bit; prevent melting with correct speeds
HDPE / Plastics Yes Yes Single flute bit; good chip clearance needed
Aluminum (6061) Yes Yes Single flute bit; slow feed; shallow passes; cutting fluid recommended
Foam (tooling foam, rigid) Yes Yes Very easy to machine; watch for static buildup with chips
Carbon fiber / Fiberglass Caution Caution Extremely hazardous dust — full respiratory protection required; consult staff before attempting

❌ Do Not Cut These Materials

Material Why
PVC / Vinyl Toxic fumes when machined
Polycarbonate Melts and chips unpredictably; poor results and fumes
Steel / Hardened metals Machine is not rated for ferrous metals
Any material of unknown composition Always verify material before cutting

Safety Rules

  • Always wear eye protection — chips and dust fly unpredictably
  • Hearing protection recommended for long jobs — the router is loud
  • Never reach into the cutting area while the machine is running
  • Keep hands away from the bit at all times — the DeWalt DW618 spins at up to 24,000 RPM
  • Always stay by the machine while it's running — never leave a running job unattended
  • If something looks or sounds wrong: click Pause G-Code File in UGS to pause, or Soft Reset to stop immediately
  • Turn off the router before making any adjustments to workholding or bit height
  • Dust collection must be running before starting any job — wood and MDF dust is a fire and health hazard

See Emergency Procedures on the main laser page for emergency contact and first aid kit location.

Helpful Tips

Always Air Cut First

Before cutting your actual material, raise Z by 10–20mm and run the job — watch the toolpath trace out and confirm it matches your expectations. This catches origin errors before they cost you material.

Tabs

For profile (cutout) operations, always add tabs in VCarve to keep parts from flying loose when the last pass finishes. Set tabs to at least 3mm high and 6–8mm wide for most work.

Climb vs. Conventional Milling

  • Conventional milling (default) — safer for wood; less chance of grabbing
  • Climb milling — better finish on some materials; can grab on less rigid setups — use with caution

VCarve defaults to conventional milling, which is correct for the Mega V.

Save Your Settings

  • Save VCarve files with descriptive names (e.g., oak-box-lid-2025.crv)
  • Store files in Google Drive or on a USB drive
  • Note your bit, feed rate, DOC, and router speed alongside your project

Troubleshooting

Problem Solution
UGS won't connect Click the refresh (circular arrows) icon to re-scan ports; try a different COM port; check USB cable is seated in the electronics box
Controller State shows ALARM Click Turn Off Alarm Lock in Common Actions; if caused by a homing switch, also jog off the switch afterward; re-home before running
Machine won't home Check USB connection; confirm controller is powered on; check that homing switches are not physically obstructed
Lost connection mid-job Disable laptop sleep/screensaver before running long jobs; check USB cable
Binding on X or Y axis Loosen the rack; move gantry to front/right of machine; check pinion gear engagement with rack; tighten front screw; move to next rack screw and repeat until reaching back/left of machine. Contact support@millrightcnc.com if binding continues.
Bit breaking Feed rate or DOC too aggressive; wrong bit for material; bit not secured properly in collet; material shifting during cut
Chatter / vibration Feed rate too fast; bit too long; workholding loose; reduce DOC and feed rate
Rough surface finish Bit dull; feed rate too fast; step over too large; try a finishing pass at higher speed and shallower DOC
Job running in wrong location Work zero not set correctly — confirm VCarve origin matches where you zeroed on the machine; check the UGS visualizer origin marker
Wrong post processor used Re-save toolpaths from VCarve using Grbl (mm) or Grbl (inch); from Fusion 360 use Grbl / grbl under Actions → Post Process
