| Property | ELEGOO Centauri 2 ComboCOREXY | ELEGOO Neptune 3 ProBEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | ELEGOO |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri 2 Combo - the Centauri 2 sold with the CANVAS multicolour unit[1] | ELEGOO Neptune 3 Pro[2] |
| Release date (announcement and actual shipping) | Not documented | Listed on the ELEGOO US store from 11 November 2022 (Shopify publish date)[3] |
| Street price (USD; dated snapshot per entry) | Not documented | $259.99 on us.elegoo.com, Aug 2026, with the compare-at price also $259.99 - notably more than the newer and far faster Neptune 4 at $219[3][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Same printer as the bare Centauri 2 for every motion, hotend, bed and electronics figure; what the Combo adds is 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection, and what it costs is bench space - 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting and air filter remain optional expansions on both[1] | The last Neptune 3 still listed; the 3 Plus and 3 Max are gone from the store's Neptune section. Do not read Neptune 4 figures onto it: the 3 Pro runs Marlin, not Klipper, tops out at 180 mm/s rather than 500, uses a 36-point mesh rather than 121-point, and its nozzle stops at 260 C rather than 300 C. Its machine size, 475 x 445 x 515 mm, is identical to the Neptune 4's, so body dimensions will not tell them apart[2][5][6] |
| Market position: superseded? successor announced? | Not documented | Superseded by the Neptune 4 series and, in ELEGOO's current marketing, by the Centauri line[6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm; printing platform 260 x 260 mm[1] | 225 x 225 x 280 mm; printing platform 235 x 235 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 586 mm with the CANVAS unit fitted[1] | 475 x 445 x 515 mm - the same body as the Neptune 4. ELEGOO's maximum size for machine activity is 475 x 580 x 725 mm[2][5] |
| Net weight (kg) | 15.5 kg net, 19 kg gross[1] | 8.1 kg net, 10.15 kg gross[2] |
| Frame construction & material | Rigid aluminium frame (Centauri 2 platform)[1] | CNC-machined aluminium extrusion frame (Neptune family)[5] |
| Enclosure: open / enclosed; panel material; door/lid | Not documented | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with dual 4260 stepper motors[1] | Cartesian i3 bed-slinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Two lead screws[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | "Silent Drive (All Axes)"; no driver part number published[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, recommended 250 mm/s[1] | 30-180 mm/s, with 60 mm/s given by ELEGOO as the recommended speed - a pre-Klipper machine, and the slowest in this file apart from the OrangeStorm Giga[2] |
| Recommended/typical print speed | 250 mm/s recommended printing speed[1] | 60 mm/s recommended printing speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default 10000 mm/s2[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Dual-gear direct extruder with 2 fans[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | Brass nozzle, 0.4 mm, titanium-alloy heat break[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature[1] | 260 C claimed max nozzle temperature - 40 C below the Neptune 4 series[2][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | 100 C max heated bed temperature at 25 C ambient[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | PEI spring steel sheet[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling plus partial bed levelling[1] | 36-point auto-levelling (the Neptune 4 family moved to 121 points)[2][7] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto tangle detection, RFID filament detection, auto refill, auto filament unloading and power-loss recovery[1] | Filament run-out sensor and power-loss recovery[2] |
| Multi-material/multi-color capability or official upgrade path | CANVAS four-colour printing with RFID filament identification and automatic refill - the defining difference from the bare Centauri 2[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Powerful Self-Developed Motherboard"[1] | Not documented |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated[1] | 300 W rated power, 24 V output[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended[1] | Marlin - ELEGOO names the system "Marlin" for the Neptune 3 Pro, against "Klipper" for the whole Neptune 4 family[2][7] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch colour capacitive touch screen[1] | 4.3-inch colour capacitive touch screen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; STL, OBJ, 3MF and STEP input[1] | Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | TF (microSD) card and USB cable only - no LAN and no Wi-Fi[2] |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, PLA-CF, TPU. Not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[1] | PLA, TPU, PETG, ABS, ASA - no Nylon, unlike the Neptune 4 family[2][5] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Operating sound published as 48 dB or less - a manufacturer figure with no distance or method stated[2] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[8] | 12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[8] |
Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
