Elegoo Centauri Carbon vs Anycubic Kobra S1: the two budget enclosed CoreXYs
The Elegoo Centauri Carbon (a 256 mm cube, hardened nozzle and gears, $299 at launch) and the Anycubic Kobra S1 (a 250 mm cube, about $420 alone or $550 as a Combo with the ACE Pro) are the two enclosed CoreXYs that undercut the Bambu Lab P1S. The Centauri Carbon wins on price, bed and abrasive filament; the Kobra S1 wins on multi-colour, because the ACE Pro exists for it and dries filament while it feeds. Single material: Elegoo. Colour: Anycubic.The short version
Who should buy which
Both printers are in SpeakCAD's slicer catalog with their official OrcaSlicer profiles, so this page has no printer to sell you. The numbers in the table come from those profiles; the prices are the makers' launch prices, and prices moved in 2025 and differ by region.2
Buy the Kobra S1 if…
You want multi-colour in an enclosed printer for under the P1S Combo price, and the drying box appeals for PETG.3
Either way, the first custom part
Describe it with its measurements, check it on a virtual bed the size of the printer you chose, and download G-code for the Centauri Carbon or G-code for the Kobra S1, sliced with its official profile. The first render usually appears within a minute or two: a new part gets deeper reasoning through the geometry, and small edits land in seconds.Elegoo Centauri Carbon vs Anycubic Kobra S1: the numbers

Parts that fit both beds
Copy one, change the numbers to yours. Each opens in the editor with the text already typed.“A hinged box 120 x 80 x 40 mm with a print-in-place hinge (0.4 mm clearance), a snap latch on the front, 1.6 mm walls.”
Open this prompt in the editor“A Raspberry Pi 5 case with a 30 mm fan grille, GPIO ribbon slot and two keyhole wall mounts, 2 mm walls, screwed lid on M2.5 pillars.”
Open this prompt in the editor“A headphone hook that screws to the side of a desk with two 4.5 mm holes 40 mm apart, a 30 mm deep arm with a 20 mm rounded end, 3 mm thick.”
Open this prompt in the editorWhat they share
Enclosed CoreXY, 250 mm class beds, 320 °C hotends, cameras, touchscreens, Wi-Fi, and OrcaSlicer-based slicers. Both print ABS and ASA well at this size; neither has a heated chamber.
Where the Centauri Carbon wins
- Price: $299 against about $420 at launch.
- Bed: 256 x 256 x 256 mm against 250 x 250 x 250 mm.
- Hardened nozzle and extruder gears as standard.
Where the Kobra S1 wins
- Multi-colour: the ACE Pro (Combo) holds four spools and dries them; the Centauri Carbon had no colour system at launch.
- Anycubic's app for cloud monitoring and sending.
What both give up
Passive chambers, so large nylon parts are beyond both. Younger software than Bambu's. Neither takes a G-code file straight from a phone browser.
Prices
Launch prices above; both changed in 2025 and vary by region.
Verdict
The Centauri Carbon is the better single-material printer and the better price. The Kobra S1 Combo is the one to buy if colour is the reason you are looking at an enclosed printer.
Sliced for either one
SpeakCAD ships the OrcaSlicer profiles of the Elegoo Centauri Carbon and the Anycubic Kobra S1, like 380+ other printers. Describe a part in plain English on a phone or a computer, watch it render on a virtual bed of the size above, change it by chat, and download G-code for the Centauri Carbon or G-code for the Kobra S1, with the print time and filament weight. The STL and 3MF are always there for your own slicer. The Elegoo Centauri Carbon and Anycubic Kobra S1 pages have prompts sized for each bed and the library parts made for them.
Questions
The Centauri Carbon, which ships a hardened nozzle and gears. Check the Kobra S1's current specification for its nozzle material before printing abrasive filament on it.
Not at launch. Check Elegoo's site for what has shipped since; when this page was written the Kobra S1 Combo was the multi-colour option in this pair.
On single-material print quality, close. The P1S is ahead on software polish, community and the AMS chaining to 16 spools; these two are ahead on price, and the Centauri Carbon on the hardened nozzle.
Yes, both, with the OrcaSlicer profile each maker ships: G-code for the Centauri Carbon and G-code for the Kobra S1, or an STL or 3MF for your own slicer. The bed sizes in the table are the ones the viewer shows while you design.
