🚨 Important Note for 1-Pack Units (Freight Damaged)

These single units often have smashed glass doors and may include bent frames, broken bed brackets, missing accessories, or other defects. No functional testing performed — glass shard cleanup risks damaging Z-screws, fans, belts, motherboard, etc. Purchase only if you're experienced with repairs.

Key Purchase Information

Listing photos show typical average condition of damaged units — yours may vary slightly.

2-Pack: Paired units with complementary defects → to rebuild 1 fully functional printer out of 2, or replacement parts are on us.
1-Pack: Single defective unit, great as a donor. Leave a note at checkout if you prefer to avoid/deal with specific defects (e.g., frame, hotend, mainboard).

Common Issues & Error Codes on Elegoo Centauri Series

Most reported problems (from users and Elegoo sources) — many are fixable via cables, parts, or tweaks, but some require mechanical skill:

Bad/loose USBC cables → Common cause of 101, 103 errors (heating failures)
Freight damage → Bent frames, broken bed brackets, smashed glass doors
Booting issues / stuck on input shaper → Usually caused by bent frame misalignment affecting sensors/motion calibration
Other frequent codes:
- 101: Heated bed didn't heat as expected
- 102/104: Thermistor (NTC) reading anomaly (bed or hotend)
- 103: Hotend not heating (check USBC cable first!)
- 502: Leveling sensor data error (loose connection, bad sensor, or tilt)
- 701: Mainboard fan abnormal
- 702: Hotend cooling fan (heat-break) abnormal (wiring/connection)

Many resolved with cable swaps, part replacements, or firmware reflashes — see Elegoo's wiki for guides.

Buyer Beware – Realistic Expectations

These are not beginner-friendly plug-and-play units. Expect significant work and potential frustration — only buy if you have solid experience with advanced 3D printer repairs. Common challenges include:

Rebuilding or unclogging hotends (often heavily gunked or damaged; may require full disassembly and part swaps).
Reflashing or troubleshooting firmware (errors can persist even after updates; custom/community fixes sometimes needed).
CoreXY belt tensioning and alignment — Improper tension leads to ringing, artifacts, layer shifts, or failed prints.
Mechanical fixes for freight damage (straightening bent frames, replacing brackets, realigning axes — can be time-consuming and may need custom parts).
General troubleshooting of fans, sensors, wiring, and motion systems — not quick fixes; debugging required

These are serious repair projects for experienced tinkerers. If you're not comfortable with mechanical/electrical work or trial-and-error, consider a new printer instead.

Included Accessories (Used, Normal Wear)

For 2-pack projects, includes one complete set:

1× Power Cord
1× PEI Plate
1× Touchscreen Controller
1× Spool Holder
1× Hotend (Rebuilding/cleaning typically required)

Centauri Model Comparison – Carbon vs Carbon 2

Both share the same high-speed enclosed CoreXY foundation — Carbon 2 adds major features for multi-color and advanced use.
