Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 2 Max[1]ELEGOO Neptune 4 Plus[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 31 August 2023 (Shopify publish date)[1]Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date), the same date as the Neptune 4 Max[3][4]
Street price (USD; dated snapshot per entry)$639.00 on store.anycubic.com, Aug 2026[1]$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[3][5][4]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Largest Kobra 2. Shares the Plus's 90 C bed ceiling and 500/300 mm/s figures but scales to 420 x 420 x 500 mm and 21 kg. Anycubic's on-page comparison is against the older Kobra Max (450 x 400 x 400 mm, Bowden, 180 mm/s), not against the Kobra 2 Plus. Note the newer Kobra 3 Max has the same 420 x 420 x 500 mm volume - build volume alone will not distinguish them[1][6][7]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][8][9][10]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable500 x 420 x 420 mm stated HWD, i.e. 420 x 420 x 500 mm; Anycubic quotes 88.2 L[1]320 x 320 x 385 mm; printing platform 330 x 330 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)740 x 735 x 640 mm stated HWD - footprint about 735 x 640 mm; this is a floor- or bench-dominating machine[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)21 kg[1]14.4 kg net, 16.65 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame (Neptune 4 family)[8]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame, no enclosure[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger with double metal spindles on X and Y and included belt tensioners[1]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashDual-motor dual Z axis[1]Two lead screws with two tie rods[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"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 maximum print speed (Anycubic Lab figure)[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 speed300 mm/s typical print speed (manufacturer figure)[1]250 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)Not documented12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)One-click vibration compensation on X/Y plus flow control[1]Not documented
Extruder
Type (direct drive / bowden) & design nameDirect extruder with double gears[1]Dual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[2][10]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle, 0.4 mm, with a titanium-alloy heat break[2]
Max nozzle temp claimed AND firmware max temp limit (both values)260 C nozzle temperature ceiling; 0.4 mm replaceable nozzle[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit90 C hotbed temperature ceiling[1]100 C max heated bed temperature at 25 C ambient[2]
Bed surface (material, texture, coating), single/double-sidedPEI magnetic spring steel plate, 420 x 420 mm[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)Anycubic LeviQ 2.0 automatic levelling, 49-point, with smart Z-offset[1]Manual levelling combined with 121-point auto-levelling[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection fitted as default[1]Filament run-out sensor and power-loss recovery; no camera, no clog detection, no auto filament unloading[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU is published[2]
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxCortex-A7 1.2 GHz processor; 8 GB built-in storage[1]Not documented
Total rated power drawNot documented320 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)Not documentedKlipper (ELEGOO names the system "Klipper" outright for the Neptune 4 Plus, rather than the ELEGOO OS branding used on the Centauri machines)[2][10]
Connectivity, UI & Camera
Display: size, type, touch?Not documented4.3-inch colour capacitive touch screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Not documentedColour capacitive touch UI; ElegooSlicer is recommended, with Orca and Cura also supported[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveNot documentedUSB, LAN and Wi-Fi[2]
Materials Support
Officially supported filament listPLA, ABS, PETG, TPU (Kobra 2 family list)[11]PLA, TPU, PETG, ABS, ASA, Nylon[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating 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)One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[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[13]

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.
