| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon 2 Combo[1] | ELEGOO Neptune 4 Plus[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 9 August 2026 (Shopify publish date)[3] | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[4][5] |
| Street price (USD; dated snapshot per entry) | $399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[3] | $309.00 on us.elegoo.com, Aug 2026, against a compare-at price of $425.00. Only a Ribbon-Cable printhead variant is listed for the Plus, unlike the Neptune 4 and 4 Max which also offer a Type-C version[4][6][5] |
| 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][7][8][9] | Middle model of the Neptune 4 family. Against the base Neptune 4: bigger (320 x 320 x 385 mm), but a lower bed ceiling (100 C rather than 110 C) and much lower acceleration (12000 rather than 20000 mm/s2). Against the Max: smaller and lighter (14.4 kg against 18.1 kg) but with a higher bed ceiling (100 C against 85 C) and higher acceleration (12000 against 8000). Its Z drive is 2 lead screws with 2 tie rods, where the Centauri machines use 3 lead screws[2][10][11][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] | 320 x 320 x 385 mm; printing platform 330 x 330 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 500 x 480 x 743 mm with the CANVAS unit fitted[1] | 533 x 517 x 638 mm; ELEGOO also publishes a maximum size for machine activity of 578 x 750 x 860 mm including rack and tray, so allow 750 mm of depth[2] |
| Net weight (kg) | 19.35 kg net, 23.8 kg gross[1] | 14.4 kg net, 16.65 kg gross[2] |
| Frame construction & material | Integrated die-cast aluminium construction (Centauri Carbon platform)[8] | CNC-machined aluminium extrusion frame (Neptune 4 family)[10] |
| 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[7][8] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[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 with two tie rods[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[1] | "Silent Drive (All Axes)" is all ELEGOO publishes; the driver part number is not given on the product page[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given as the recommended speed[1] | 30-500 mm/s printing speed, with 250 mm/s given by ELEGOO as the recommended figure - the 500 mm/s number is a ceiling, not a working speed[2] |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | 250 mm/s recommended printing speed (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default 10000 mm/s2[1] | 12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | Dual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[2][8] |
| 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, with a titanium-alloy heat break[2] |
| 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][8] | 300 C claimed max nozzle temperature[2] |
| 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 | Dual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1] | PEI spring steel sheet; ELEGOO notes it is now upgraded to a dual-sided textured PEI + PLA-specific surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling with full-auto calibration[1] | Manual levelling combined with 121-point auto-levelling[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[1] | Filament run-out sensor and power-loss recovery; no camera, no clog detection, no auto filament unloading[2] |
| 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] | ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU is published[2] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output[1] | 320 W rated power; 24 V output; 110-120 V / 220-240 V input[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS; ElegooSlicer recommended, Orca and Cura supported[1] | Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 Plus, rather than the ELEGOO OS branding used on the Centauri machines)[2][8] |
| 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][8] | 4.3-inch colour capacitive touch screen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; LED lighting fitted; STL, OBJ, 3MF and STEP input[1] | Colour capacitive touch UI; ElegooSlicer is recommended, with Orca and Cura also supported[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and Wi-Fi[1] | USB, LAN and Wi-Fi[2] |
| 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] | PLA, TPU, PETG, ABS, ASA, Nylon[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][8] | Operating sound is published as 65 dB or less - a manufacturer figure with no measuring distance or method given, so it is not comparable with a reviewer's dB reading[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[12] | 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[12] |
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.
