SpeakCAD for the Elegoo Centauri Carbon
Custom parts for the Elegoo Centauri Carbon: describe them, download G-code sliced for it
Elegoo's enclosed CoreXY with a 256 mm cube and a hardened hotend for carbon-fibre filaments. SpeakCAD ships the Elegoo Centauri Carbon's own OrcaSlicer profile: describe a part in plain English, watch it render on a virtual 256 x 256 mm bed, edit it by chat, and download a .gcode file, ready for the SD card, the USB stick or the printer's own upload page. Or take the STL or 3MF to your usual slicer. Runs in Safari and Chrome, on a phone or a computer, nothing to install.
How it works
From a sentence to the Centauri Carbon's SD card
The slicer runs on our side with the same profiles OrcaSlicer ships for the Elegoo Centauri Carbon. You choose the print profile and the filament; the printer settings are already right.2
Check it on the Centauri Carbon's bed
The part renders on a virtual bed the size of the Centauri Carbon's. The first render usually appears within a minute or two: a new part goes to the strongest models, which reason through the geometry, and small edits land in seconds. Turn it, tap a face to read a size, open the dimensions panel, and see whether it has overhangs that need supports. Anything wrong is one sentence to fix.3
Pick the Elegoo Centauri Carbon and its profile
In the download dialog choose the Elegoo Centauri Carbon (0.2 nozzle, 0.4 nozzle, 0.6 nozzle, 0.8 nozzle), one of its print profiles (0.08 mm, 0.1 mm, 0.12 mm, 0.14 mm…), a filament, then infill, walls, supports and adhesion. The printer and its last settings are saved to your account.4
Download and print
You get a .gcode file, ready for the SD card, the USB stick or the printer's own upload page, with the estimated print time and filament weight. Re-slicing a design you already downloaded does not spend the 10 credits again; without Pro or Unlimited each slice still spends 5 credits.The Elegoo Centauri Carbon profile SpeakCAD slices with

Prompts sized for the Centauri Carbon
Copy one, change the numbers to yours. Each opens in the editor with the text already typed.“A purge bucket for an Elegoo Centauri Carbon: hooks over the rear purge opening with a 10 mm lip, 60 mm wide chute into a 90 x 70 x 110 mm bin, 2 mm walls, PETG.”
Open this prompt in the editor“Riser feet for the Centauri Carbon: four 45 x 45 mm pads 30 mm tall with a 5 mm recess for the stock feet, 3 mm walls, 25 percent infill.”
Open this prompt in the editor“A top PTFE guide for the Centauri Carbon: 4 mm tube hole with a 608 bearing roller, two M3 holes 30 mm apart, 2.4 mm walls.”

Slicing is the step that keeps 3D printing on the desktop: a design made anywhere still has to pass through Bambu Studio, PrusaSlicer or Cura on a computer. SpeakCAD runs OrcaSlicer on its own servers with the profile OrcaSlicer ships for the Elegoo Centauri Carbon, so the phone that typed the description also downloads G-code. The desktop slicer stays the better choice for arranging many parts on one bed or for exotic settings; for one part at a time, the download dialog covers the profile, the filament, infill, walls, supports and adhesion.
Parts that fit the Centauri Carbon
The Elegoo Centauri Carbon's 256 x 256 mm bed and 256 mm height are what the virtual bed in the viewer shows, so a part that looks too big is too big. Ask for a part to be split into two halves with alignment pins when it does not fit, or for a flat print orientation when it would need supports. The examples above and the library parts below all fit.
Parts that fit the first time
The Elegoo Centauri Carbon prints slightly differently from the next printer, which is why holes come out tight and lids loose. Fit Check cuts a five-minute test slice from the interface that must fit, you report too tight, perfect or too loose, and every model after that is built with the clearance your Centauri Carbon needs. The test slice downloads free as STL or 3MF. How Fit Check works.

Questions
Yes. The Elegoo Centauri Carbon is one of the 380+ printers in the slicer catalog, with 4 nozzle variants and the print and filament profiles OrcaSlicer ships for it. Pick it in the download dialog and download G-code; it is saved to your account for next time.
No. SpeakCAD slices on its servers and gives you a .gcode file. Copy it to the SD card or USB stick the Centauri Carbon takes, or upload it through the printer's own web page or app. If you prefer your own slicer, download the STL or 3MF instead.
The print profile (layer height and speed presets from the Elegoo Centauri Carbon's profile), the filament profile (the printer's own and the OrcaSlicer library: Generic PLA, PETG, ABS, ASA, TPU, carbon-fibre blends and hundreds of branded filaments), infill, wall count, supports and bed adhesion. Nozzle temperature, bed temperature and speeds come from the profiles you pick.
The virtual bed in the viewer is sized from the Elegoo Centauri Carbon's profile (256 x 256 mm), so you see it before slicing. Ask for the part to be split into two pieces with alignment pins or a dovetail, or for a different orientation; each is one sentence.
Sliced downloads are included in Pro ($9.99 a month, 200 credits) and Unlimited ($24.99 a month); with Starter credits ($5 once for 75 credits, no subscription) a sliced download spends 5 credits on top of the usual 10. Re-slicing a design you already downloaded does not spend the 10 credits again; without Pro or Unlimited each slice still spends 5 credits. STL and 3MF downloads are always available.
Yes. The editor runs in Safari on iPhone and iPad and in Chrome on Android; the file lands in Files or Downloads, ready for the card or the printer's app. The same project opens later on a desktop.
