'''⚠️ SAFETY WARNING: The Centauri Carbon uses a heated nozzle (up to 320°C) and heated bed (up to 110°C). Never reach inside during operation. Allow parts to cool before removing.'''

'''⚠️ Do not open the front door or top cover during a print, especially with ABS/ASA — this releases fumes and disrupts chamber temperature.'''

The '''Elegoo Centauri Carbon''' is a fully enclosed CoreXY 3D printer and one of GRM's primary 3D printing workhorses (the shop runs five Gen 1 units). It ships nearly ready to print with full auto-calibration, a hardened steel nozzle, and an enclosed chamber, making it capable of everything from basic PLA to carbon-fiber-reinforced and engineering-grade filaments.

== Overview ==
The '''Centauri Carbon''' is GRM's everyday high-performance FDM printer. The hardened steel nozzle and extruder handle abrasive filaments (carbon/glass-fiber) with no upgrade needed, and the enclosed chamber allows warp-prone materials like ABS and ASA. Note that it does '''not''' have an active chamber heater, so extremely temperature-sensitive materials like polycarbonate can be inconsistent despite the 320°C nozzle ceiling. A built-in chamber camera enables remote monitoring.

== Software ==
Prepare files using '''Elegoo Slicer''' (recommended, based on Orca) or Orca Slicer, both of which include tuned profiles for the Centauri Carbon.

* See [[Slicer_Basics|Slicer Basics]] for GRM's general slicing guidance.

'''Getting files to the printer — two methods:'''

{| class="wikitable" style="width:100%;"
|-
! Method !! How
|-
| '''Remote send (Wi-Fi/LAN)''' || In Elegoo Slicer, slice your file, then send the job directly to the printer over the network. The job appears on the printer's touchscreen for you to start.
|-
| '''USB drive''' || Export the sliced file to the included USB drive, plug it into the printer, and select the file from the touchscreen.
|}

== Startup ==
# Power on the printer using the switch at the rear.
# Load filament into the side-mounted spool holder; the run-out sensor will detect it.
# Send your sliced file via remote send or USB drive (see Software above).
# On the touchscreen, select the print job.
# The printer runs auto-leveling and calibration before starting.
# Monitor the first layer to confirm good bed adhesion.

== Materials ==
{| class="wikitable" style="width:100%;"
|-
! Material !! Status !! Notes
|-
| PLA / PLA+ || ✅ || Use the smooth PLA cool plate; open the door for better airflow.
|-
| PETG || ✅ || Good layer adhesion; use textured PEI side.
|-
| ABS / ASA || ✅ || Keep door and top cover closed for chamber heat; ensure ventilation.
|-
| TPU || ✅ || Dual-gear extruder handles flexibles well; print slower.
|-
| PLA-CF / PETG-CF / other CF || ✅ || Hardened nozzle is standard — no upgrade needed.
|-
| PA / PC (nylon, polycarbonate) || ⚠️ || Possible within thermal limits, but no active chamber heater — results can be inconsistent.
|-
| style="background:#ffe4e4;" | Filaments with unknown/no temp data || style="background:#ffe4e4;" | ❌ || style="background:#ffe4e4;" | Do not print without verified temperature settings.
|}

== Safety ==
<div style="background:#fff3cd; border: 2px solid #f0a500;">
* Do not open the enclosure during a print, especially with ABS/ASA — fumes and heat loss can occur.
* Never touch the nozzle or bed during or immediately after printing.
* Ensure the room is ventilated when printing high-temp materials — the built-in filter helps but does not replace ventilation.
* Keep the automated filament cutter and purge area clear of hands during operation.
</div>

== Troubleshooting ==
{| class="wikitable" style="width:100%;"
|-
! Issue !! Fix
|-
| Print not sticking || Clean the plate with IPA; re-run auto leveling; confirm you're using the correct plate side for the material.
|-
| Remote send fails || Confirm the printer and computer are on the same network; check Wi-Fi/LAN binding in the slicer.
|-
| Filament not loading || Cleanly cut the filament end; confirm the run-out sensor registers it; reload the spool.
|-
| Clogs/under-extrusion || Verify nozzle temp matches material; use the included unclogging pin; check for heat creep on long high-temp prints.
|-
| USB not reading || Reformat drive to FAT32; confirm files exported correctly from the slicer.
|-
| PC/nylon warping || Expected without an active chamber heater; use adhesion aids and keep the enclosure sealed.
