Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)ELEGOO Centauri Carbon 2 Combo[1]ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[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 27 May 2023 (Shopify publish date)[4]
Street price (USD; dated snapshot per entry)$399.00 on us.elegoo.com, Aug 2026, against a compare-at price of $449.00[3]$219.00 on us.elegoo.com, Aug 2026, against a compare-at price of $249.00; both the Ribbon-Cable and Type-C printhead variants are the same price[4]
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][5][6][7]Two printhead variants of the same machine are sold under one SKU - "Ribbon-Cable Version" and "Type-C Version" - which use different printhead parts. Within the Neptune 4 family the numbers diverge sharply and get mixed up constantly: Neptune 4 is 225 x 225 x 265 mm with a 110 C bed and 20000 mm/s2; the Plus is 320 x 320 x 385 mm with a 100 C bed and 12000 mm/s2; the Max is 420 x 420 x 480 mm with an 85 C bed and only 8000 mm/s2. The Neptune 4 Pro is a separate model again[4][2][8][9]
Market position: superseded? successor announced?Not documentedStill listed in ELEGOO's US store Neptune section in Aug 2026 alongside the 4 Pro, 4 Plus and 4 Max, but ELEGOO's current development is on the Centauri line[7]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable256 x 256 x 256 mm; printing platform 260 x 260 mm[1]225 x 225 x 265 mm; the PEI platform itself is 235 x 235 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)500 x 480 x 743 mm with the CANVAS unit fitted[1]475 x 445 x 515 mm. ELEGOO separately publishes a "maximum size for machine activity" of 475 x 550 x 735 mm including rack and tray - the depth to allow for is 550 mm, not 445 mm[2]
Net weight (kg)19.35 kg net, 23.8 kg gross[1]8.3 kg net, 10.6 kg gross[2]
Frame construction & materialIntegrated die-cast aluminium construction (Centauri Carbon platform)[6]CNC-machined aluminium extrusion frame[2]
Enclosure: open / enclosed; panel material; door/lidFully 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[5][6]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-backlashThree lead screws with three linear guide rods[1]Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[1]
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; no driver part number is given[1]
Speed & Acceleration
Max print speed (claimed, mm/s)500 mm/s or less, with 250 mm/s given as the recommended speed[1]500 mm/s max toolhead speed (manufacturer claim); the Neptune 4 Plus page for the same family states a recommended 250 mm/s[2][8]
Recommended/typical print speed250 mm/s recommended printing speed (manufacturer figure)[1]250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[1]
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration; default 10000 mm/s2[1]20000 mm/s2 max toolhead acceleration (manufacturer claim) - notably higher than the Plus at 12000 and the Max at 8000, because the moving mass is smaller[2][8][9]
Extruder
Type (direct drive / bowden) & design nameDual-gear direct extruder with one fan[1]Dual-gear direct extruder with 2 fans[1]
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 copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[1]
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][6]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C max heated bed temperature at 25 C ambient[1]110 C max heated bed temperature[2]
Bed surface (material, texture, coating), single/double-sidedDual-sided spring steel sheet, textured PEI plus a PLA-specific surface[1]PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[1]
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; no full-auto calibration on this model[1]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor, clog detection, auto filament unloading and power-loss recovery[1]Filament detection fitted; power-loss resume printing supported[2]
Multi-material/multi-color capability or official upgrade pathCANVAS 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 published[1]
Input voltage (110/220 V, switch or auto)Not documented115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[2][1]
Total rated power draw1100 W at 220 V, 350 W at 110 V rated; 24 V output[1]310 W rated power, 24 V output[1]
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 series, rather than the ELEGOO OS branding used on the Centauri machines)[1][6]
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][6]4.3-inch colour capacitive touch screen[1]
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 recommended, with Orca and Cura also supported[1]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB and Wi-Fi[1]LAN and USB file transfer; no Wi-Fi is listed for the base Neptune 4, unlike the Plus (USB/LAN/Wi-Fi) and Max (Wi-Fi/USB/WLAN)[2][8][9]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Camera fitted[1]Not documented
Materials Support
Officially supported filament listIdeal: 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][6]Operating sound published as 60 dB or less - a manufacturer figure with no distance or method stated, so it is not comparable with an independently measured reading[1]
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[10]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[10]

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.
