Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 2[1]ELEGOO Neptune 4 Plus[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 15 May 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)$169.00 on store.anycubic.com, Aug 2026, against a compare-at price of $279.00 - the cheapest machine in this file[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)Base model of a five-way family that is easy to confuse. All of Kobra 2, Kobra 2 Neo and Kobra 2 Pro share the same 220 x 220 x 250 mm build volume, but their speed ceilings differ: Neo 250 mm/s max / 150 typical, Kobra 2 300 / 200, Kobra 2 Pro 500 / 300. The Plus (320 x 320 x 400 mm) and Max (420 x 420 x 500 mm) are bigger but drop the bed ceiling to 90 C where the three small ones reach 110 C. Anycubic's own note: Kobra 2 firmware must be at V3.0.6 or above for the quoted speed[1][6][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][12]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 220 x 220 mm stated HWD, i.e. 220 x 220 x 250 mm in X x Y x Z; Anycubic quotes 12.1 L[1]320 x 320 x 385 mm; printing platform 330 x 330 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)486 x 440 x 435 mm stated as HWD, so the desk footprint is about 440 x 435 mm and the height is 486 mm[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)8.4 kg[1]14.4 kg net, 16.65 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame (Neptune 4 family)[10]
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 a gantry frame; Anycubic describes double metal spindles with SG15 bearings on the moving axes[1]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashDouble-threaded rod Z axis (dual lead screws)[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)300 mm/s maximum print speed (Anycubic Lab figure; firmware V3.0.6 or above required)[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 speed200 mm/s recommended print speed (manufacturer figure) - the number to plan around, not the 300 mm/s headline[1]250 mm/s recommended printing speed (manufacturer figure)[2]
Max acceleration (claimed, mm/s²)3000 mm/s2 acceleration (manufacturer figure) - modest next to the 20000 mm/s2 of the current Kobra generation[1][13]12000 mm/s2 maximum acceleration; default acceleration 5000 mm/s2[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive with a dual-geared extrusion structure[1]Dual-gear direct extruder with 2 fans (the Centauri machines use a 1-fan version)[2][12]
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]
Heater cartridge power (W)60 W hotend heater (Anycubic states "upgraded extruder power reaches up to 60 watts")[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C hotbed temperature ceiling[1]100 C max heated bed temperature at 25 C ambient[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedPEI 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 with smart Z-offset and a user-adjustable Z compensation value[1]Manual levelling combined with 121-point auto-levelling[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out sensor fitted, with power-loss recovery[1]Filament run-out sensor and power-loss recovery; no camera, no clog detection, no auto filament unloading[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designPart-cooling fan rated to 7000 rpm (Anycubic figure)[1]Not documented
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]
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][12]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch colour LCD touchscreen[1]4.3-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-drivemicroSD card[1]USB, LAN and Wi-Fi[2]
Calibration Routines & QoL
Assembly level & time from unbox to first printModular assembly - Anycubic states 5 pieces in about 10 minutes[1]Not documented
Materials Support
Officially supported filament listPLA, ABS, PETG, TPU[1]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[14]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[15]

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.
