Im at work right now and can't do anything 😒

Hi Everyone,

We now have CC1 Canvas and CC2 Combo CAD. See below for status of each-

• CC1 CANVAS: essentially finished including all accessories and internal geometry barring minor CANVAS gearbox housing refinement), and preliminary CC2 combo CAD.
• CC2 Combo: is more preliminary and is a mixture of a CC1 base, CANVAS parts, and the CC2 frame and purge bin Elegoo released (which unfortunately accidentally was the emoji edition verticals so spool holders are dropped lower than they should be. Additionally only rough CAD is available for part of the thermal shield, and the revised CC2 plastic insert is not included, nor is the modified custom toolhead fan or aux/exhaust fan system.

Files for all three printers can be downloaded from our github repository which also includes FDM optimized replacement parts for the base CC1.

Additionally there are live viewers for each printer on the OC docs for each printer:

• CC1
• CC1 + CANVAS
• CC2

If you can contribute to CAD revisions, especially for CC2 as none of the CAD-focused project members have one, please create a pull request on the github, or message on the OC Discord.

Sooo, serious bed adhesion problems when trying ASA for first time and created a big nasty blob plus some dust. Unfortunately we can't retest parameters because that blob ripped off parts of the printer. Sigh. So what parts do I need to buy to bring it back to life and try again? See photos of print head and the blob.

Blob contains silicone sock, square metal bracket, ceramic plate with wires, heat sensor?

Also, would like recs on what to do to prevent recurrence.

Printer: CC1 (no canvas)

Filament: sunlu ASA white

Nozzle temp 260c (recs on temp? I saw 270c)

Bed temp: 60c (recs on temp? I saw 90c)

Cabin temp "at least 45c" per teen. Will add reflective bubble wrap insulation - inside our outside printer? Other insulation?

No glue used, is the supplied Elegoo glue ok?

Previous experience with mostly Elegoo PLA

(Backstory: busy mom who knows more about this than the dad but is working full time work and prepping for first ever backpacking trip. Teen, who knows the machine the best, was printing some parts that mom insisted on for backpacking trip when this happened. Mom feels bad for not being able to troubleshoot and/or monitor and also wants a working printer to use all that ASA that she just ordered)

A couple months back I posted pycentauri, a local network toolkit for the original Centauri Carbon. I recently got a CC2 with the Canvas, spent a week reverse engineering its protocol, and v0.6.0 now supports both printers from the same package.

UI Screenshot

The CC2 turned out to be a completely different animal: MQTT instead of WebSockets, a different command set, token auth, camera on a different port. pycentauri auto-detects which model you're pointing at, so everything works the same way on either printer.

What you get (both printers):

• Web dashboard: live camera, temps, progress/ETA, pause/resume/stop, speed mode (silent/balanced/sport/ludicrous), fan and heater control, all from any browser on your LAN
• CLI: centauri status, centauri watch, centauri snapshot, full print control
• Python library (async) if you want to build your own stuff
• RTSP bridge: re-streams the webcam as H.264 for Home Assistant, Frigate, VLC, or your NVR
• MCP server: lets AI agents (Claude, Cursor, etc.) monitor your printer and literally see the camera feed
• REST API with OpenAPI docs for anything else

New and CC2 only:

• Canvas multi-filament panel: every tray's filament, color, temp range, loaded status, plus an auto-refill toggle
• Live head speed readout (matches the printer screen)
• Filament runout sensor state
• Canvas support coming for CC1 soon

For the protocol nerds:

Everything learned the hard way is documented in the repo's PROTOCOL.md with dates and firmware versions. Highlights: the CC2 silently expires your MQTT session after about 6 minutes unless you send an app-level ping, its camera is an unauthenticated MJPEG stream on port 8080, both printers only accept exactly four print speed values, and the CC1's status push scheduler can go dormant at idle in a way that survives reboots. If you're building your own integration, this doc may help.

No cloud account, no Elegoo servers, nothing leaves your LAN. Apache 2.0.

Install: pip install "pycentauri[server]" then centauri server --host <printer-ip> (add --access-code <code> for a CC2, it's on the printer screen).

I've had my Centauri Carbon 1 for a few months. I initially printed a few terrain sets with 0.4mm and was really happy with them. Then I did a few mini with a 0.2mm with dome good results. I didn't use for a few weeks and tried to ho back to terrain at 0.4mm but have had days and days of failed prints.

I've tried a running calibration, cold pulls, scrubbingbuild plate with dish soap and rinsing ut keep getting a print bed covered in plastic spaghetti. It looks like the flow of filament is okay and the first layers are sticking but when I check back it's gone wrong.

Any ideas of what else I should try?

Hi, long time lurker, first time poster. I just received my Canvas this afternoon and got everything connected after a couple hours of tinkering. It looked like I did everything in the video, and the machine loaded up with the first startup. I installed the latest firmware update for the Canvas but now it appears that I'm stuck in a boot loop. The loading screen keeps coming up, it loads for a few seconds before shutting down and starting all over. I saw a couple of suggestions about unplugging the printhead usb cable and that at least starts the machine up before the printhead anomaly error comes up. I'm at a loss for what my next steps could be

Why do my first layers look like this? It looks like the infill doesn’t go all the way to the walls. It gets better as it fills in, but you can still see the ladder look in the final print. Is it a setting? Is it normal?

So I’m doing some research but thought someone here maybe able to identify this issue as I’m getting a bit overwhelmed with what I may need to adjust. I also think I’ve got 2 issues here.

Issue 1, the surfaces of my prints seem to be getting gouged. When I switch to BALANCED speed it seems to be better, but not 100% gone.

Issue 2, the spaghetti stringing. This is where I’m getting a bit overwhelmed, my spool has been opened for a few hours from new and most of my research seems to point to to much moisture in the spool. But it’s like newly opened so not sure if this is the issue?

Any help on the wound be greatly appreciated!

Some details:
- I’m using Elegoo Rapid PETG.
- I’m using orca slicer recommend print settings on the strength profile apart from infil density upped from 20>30%.
- I used the default auto supports that were under the spaghetti picture part.
- I’m on a brand new CC1
- I performed the 30min self test that all cleared before printing
- I’ve been running between balanced and sport speed profile.

downloading the update is working. the update self is hanging since hours.. reproduced this about 4 times

I finally got canvas up and running and now I'm trying to fine tune it, this alien bust was my first multi color print. I got this really bad color bleed between elegoo white, and this shiny red/blue. This was with default flush volume.

Next test I did a cube with dots and doubled the purge volume and it looks better but still bad.

Next I did it again and maxed out the purge volume. Bleeding fixed but of course this produces and obscene amount of poop.

I'm not 100% sure what the values mean in the flushing volumes box, so I'm pretty lost.

Please help.

So I dont have a spare nozzle at the moment, this happened in the last 10 minutes of a print, the silicon sock is also full of plastic. Is there any way you all.have rescued one of these when they've been eaten by a plastic blob?

After installing Canvas, the printer is continuously failing to pull the filament to the printhead before the print starts. It only works if I manually push it to the print head extruder. I have tried just about everything I can think of including starting with updated FW, updated slicer both Elegoo and Orca, deleted all old printer snd print profiles, reverted from Open CC back to stock 1.4.46, etc. What am I missing?
