| Property | ELEGOO Centauri Carbon 2 ComboCOREXY | Markforged Onyx OneINDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | ELEGOO | Markforged |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon 2 Combo[1] | Markforged Onyx One Desktop 3D Printer[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 9 August 2026 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The Centauri Carbon 2 sold with the CANVAS multicolour unit. Every printing figure matches the bare Centauri Carbon 2; what changes is the body - 500 x 480 x 743 mm and 19.35 kg with CANVAS fitted - and CANVAS capability being listed Yes. Against the first-generation Centauri Carbon: 350 C nozzle rather than 320 C, clog detection added, and a HEPA plus coconut-shell carbon filter stack rather than the nano mineral crystal filter. An ELEGOO x emoji collaboration edition of the same machine is also listed[1][4][5][6] | The defining limitation: the Onyx One prints Onyx only and has NO continuous-fibre reinforcement. The Onyx Pro adds fibreglass, the Mark Two adds the full continuous-fibre range, and the X7 is a much larger industrial machine. Onyx One specifications must never be read from Mark Two or X-series material lists[2][7][8] |
| 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] | 12.6 x 5.2 x 6.1 in (approximately 320 x 132 x 155 mm)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 743 mm with the CANVAS unit fitted[1] | Not documented |
| Net weight (kg) | 19.35 kg net, 23.8 kg gross[1] | Not documented |
| Frame construction & material | Integrated die-cast aluminium construction (Centauri Carbon platform)[5] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed; the Centauri Carbon 2 uses a HEPA plus granulated coconut-shell activated-carbon filter stack rather than the first generation's nano mineral crystal filter, and adds a smart exhaust grille[4][5] | Enclosed desktop cabinet[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given as the recommended speed[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| 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] | Single extruder — plastic only, no fibre channel[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 C claimed max nozzle temperature - 30 C above the first-generation Centauri Carbon[1][5] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling with full-auto calibration[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[1] | Not documented |
| Multi-material/multi-color capability or official upgrade path | CANVAS multi-material capability included - the defining difference from the bare Centauri Carbon 2[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Powerful Self-Developed Motherboard" is all ELEGOO publishes[1] | Not documented |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[1] | Proprietary; slicing and print management run in Markforged's cloud-based Eiger software[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch colour capacitive touch screen (the first-generation Centauri Carbon used a 4.3-inch panel)[1][5] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; LED lighting fitted; STL, OBJ, 3MF and STEP input[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | Not documented |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Camera fitted[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Ideal: PLA, PETG, ABS, ASA. Capable: TPU, PC, PA, PET and fibre-reinforced filaments[1] | Onyx only — Markforged's nylon filled with chopped carbon fibre. Markforged claims parts 1.4x stronger than ABS and heat deflection to 293 °F (145 °C)[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 45 dB or less - a manufacturer figure with no distance or method stated, and 10 dB below the first-generation Centauri Carbon's published figure[1][5] | Not documented |
| 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[9] | Not documented |
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.
