The Centauri 2 is Elegoo's budget CoreXY with a 256 mm build cube, a 350 degrees C nozzle and a 500 mm/s top speed, and the Combo adds the Canvas system for four colours. It is for hobbyists who want a fast, inexpensive printer with optional multi-colour.
Does the ELEGOO Centauri 2 3D printer work with SimplyPrint, OctoPrint, Mainsail and Fluidd?
Each way of connecting it, what it needs, and how to set it up.
SimplyPrint Client
Compatible
Runs ELEGOO OS like the Centauri Carbon 2, which the SimplyPrint Client connects natively; not confirmed on the Centauri 2.
Source
What you need: A computer or Raspberry Pi on the same network that stays on, running the SimplyPrint Client
ELEGOO OS (Klipper G-code flavour in ElegooSlicer), no Moonraker exposed.
Source
Doesn't ship with Klipper: it runs Klipper after you install it in place of its own firmware, a modification
What works with SimplyPrint
Connected through SimplyPrint Client, SimplyPrint supports everything the ELEGOO Centauri 2 lets other software do: the camera and AI failure detection, remote printing, skipping objects, temperature and movement control, filament mapping for its multi-material unit and AutoPrint. The only exceptions are what the ELEGOO Centauri 2 doesn't let other software do: baby stepping, send G-code, change filament, bed leveling and Z-Offset Calibration.

What slicer to use for the ELEGOO Centauri 2
Use ElegooSlicer, ELEGOO's own slicer: it has a ready-made profile for the ELEGOO Centauri 2. Also with a profile for it: OrcaSlicer.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the ELEGOO Centauri 2.
Cloud-Based Slicer for ELEGOO Centauri 2: Use ElegooSlicer Online
Use ElegooSlicer and other slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your ELEGOO Centauri 2 models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your ELEGOO Centauri 2: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.
The app for the ELEGOO Centauri 2
SimplyPrint works as the ELEGOO Centauri 2's app: on your phone and in any browser, with a slicer in the cloud.
There's no plate swapper or auto-ejection kit for the ELEGOO Centauri 2 in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
CoreXY printers push their prints off
The ELEGOO Centauri 2's bed only moves up and down, so the usual way to automate it is a G-code routine that lets the toolhead push the cooled print off the front of the plate before the next job starts.

What filament can the ELEGOO Centauri 2 print?
Filament compatibility for the ELEGOO Centauri 2: the materials ELEGOO lists for it.

Suitability
Notes
PLA
Great
On the maker's list of materials for this printer.
PETG
Great
On the maker's list of materials for this printer.
TPU & flexibles
Great
On the maker's list of materials for this printer.
ABS & ASA
With care
The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints.
Nylon (PA)
With care
Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC)
With care
On the edge - PC really wants an enclosed, hot chamber to avoid warping.
Carbon-fiber & glass-filled
Great
On the maker's list of materials for this printer.
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
Best filament for the ELEGOO Centauri 2
Filaments the ELEGOO Centauri 2 prints well, ELEGOO's own first, then the best known.
Calls it a very good, stripped-down four-color Core XY printer built on the Canvas system, the most budget-friendly she has seen, with a well-designed UI and easy 95A TPU. Cons: no camera, no lighting, no enclosure, spool holders that fit many spools poorly, and a cold plate that is not sticky enough.
“Currently on sale for $319, the Elegoo Centauri 2 Combo is the most budget-friendly four-color Core XY printer I’ve seen.”
When to choose the ELEGOO Centauri 2
Choose the Centauri 2 Combo when price is the deciding factor: Tom's Hardware, which rated it 3.5/5, called it the most budget-friendly four-colour CoreXY printer it has seen, at $319 on sale, with a well-designed interface and easy 95A TPU. It is stripped down: Tom's Hardware found no camera, no lighting and no enclosure. For ABS or ASA or a classroom, an enclosed printer such as the Bambu Lab P2S or Creality K2 is the better pick; if you do not need colour, the plain Centauri 2 costs less still.
Pros
The most budget-friendly four-colour CoreXY Tom's Hardware had seen; Elegoo lists $279 for the printer and $329 for the Combo.
A 350 degrees C nozzle, CoreXY at up to 500 mm/s and full-auto calibration (Elegoo).
A well-designed interface and easy printing of 95A TPU (Tom's Hardware).
The Combo uses Elegoo's Canvas system for four colours (Tom's Hardware).
Expected to work with SimplyPrint through the SimplyPrint Client.
Cons
No enclosure, so ABS and ASA are not what it is made for.
No camera and no lighting (Tom's Hardware), so remote watching needs an add-on.
Spool holders fit many spools poorly, and the cold plate is not sticky enough (Tom's Hardware).
The Client route is expected, not verified; Klipper is not possible and OctoPrint unlikely.
Who it suits
SchoolsCan work
Cheap and easy to use, and SimplyPrint can queue prints for approval, but it is open with no camera.
HobbyistsGreat fit
A fast four-colour CoreXY for very little money, rated well by Tom's Hardware for its value.
BusinessesCan work
Fine for PLA and PETG prototypes, but open, with no camera and limited materials.
Print farmsNot a good fit
No camera and no enclosure, and the SimplyPrint route is not yet verified, so it is a weak choice for unattended fleets.

ELEGOO is fairly open in daily use: its printers work over the LAN with open slicers and any filament, and it now publishes firmware source. Source releases have followed community pressure rather than launch, and spare parts for the newest printers are thin in its store.
Firmware and custom firmware ●●●●●
The Neptune 4 series runs Klipper. For the Centauri Carbon, which went on sale in February 2025, ELEGOO published its modified source on GitHub under GPL-3.0 in September 2025, saying it did so in response to user feedback.
[1][2][3][4]
Local control and integrations ●●●●●
ELEGOO's printers connect to its slicer on the local network by IP without an account. The Neptune 4 series serves Klipper's web interface and Moonraker, which OrcaSlicer reaches as an Octo/Klipper host. For the Centauri Carbon and Centauri Carbon 2, ELEGOO published Elegoo Link on GitHub in January 2026, an Apache-2.0 SDK for local discovery, status, file upload and print control. The Matrix phone app adds remote printing while the printer is online.
[5][4][16][6][17]
Third-party filament, slicers and parts ●●●●●
Third-party filament works; ElegooSlicer is an open-source OrcaSlicer-based slicer, OrcaSlicer works with the Neptune 4, and ELEGOO published the data format of its RFID filament tags so others can use it.
[7][8][4]
Repairs and spare parts ●●●●●
ELEGOO sells hotend, extruder and nozzle kits and some boards for the Neptune 4, and its wiki has many replacement guides, including the Centauri Carbon motherboard. The store's Centauri Carbon parts list is short (hotend kit, touchscreen, upper shell).
[9][10][11]
Data and privacy ●●●●●
LAN printing needs no account; the Matrix app and cloud do. The privacy policy names the companies responsible for personal data in each region (Shenzhen, Hong Kong, United States) but is written mainly for the online store.
[12][5]
Community and documentation ●●●●●
Active community and a wiki with guides per model; firmware and slicer sources are on GitHub, although the Centauri Carbon source came after users asked for it.
[11][7][1]
Pros
Works on the local network with ElegooSlicer or OrcaSlicer, with no account needed.
Open-source slicer and a published RFID tag format for filament.
Many step-by-step replacement guides in its wiki.
Offered owners compensation when the Centauri Carbon multi-colour add-on was delayed.
Cons
Centauri Carbon firmware source came about seven months after sales began, after users asked.
The Centauri Carbon's multi-colour add-on only became available in April 2026, after ELEGOO said in November 2025 it could not give a date.
Few complete Centauri Carbon parts are listed in its store.
The privacy policy is written mainly for the online store.
Track record
May 2026: ELEGOO's parent closed a B+ financing round of over 500 million yuan (about $73 million) from investors including Meituan, Hillhouse Capital and Shenzhen Capital Group. It reported 2025 revenue of 2.3 billion yuan.
[13]
April 27, 2026: CANVAS, the multi-colour system for the Centauri Carbon, became available, five months after ELEGOO said it could not give a release date.
[14]
November 18, 2025: DJI and Hangzhou Jiangyu Technology became shareholders of ELEGOO's parent company, according to a business registration update reported by TechNode. The size of the stake was not disclosed.
[15]
November 2025: ELEGOO said the multi-colour system it was developing for the Centauri Carbon did not yet perform as it wanted and that it could not guarantee a release date. It offered owners a choice of a $50 filament coupon, a 365-day warranty extension or $80 off a Centauri Carbon 2 Combo.
[14]
September 26, 2025: In response to user feedback, ELEGOO published the modified source code of the Centauri series firmware on GitHub under GPL-3.0.
[1][2]
February 2025: ELEGOO opened pre-orders for the Centauri Carbon, its first enclosed CoreXY printer, on 17 February 2025.
