Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 2 Neo[1]ELEGOO Neptune 4 (spec table "Product Model: Neptune 4")[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 31 August 2023 (Shopify publish date), the same day as the Kobra 2 Plus and Kobra 2 Max[1][3][4]Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[5]
Street price (USD; dated snapshot per entry)$249.00 on store.anycubic.com, Aug 2026 - higher than the better-specified Kobra 2 at $169 on the same day, which is a listing quirk rather than a positioning statement[1][6]$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[5]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Lowest model of the Kobra 2 family. Same 220 x 220 x 250 mm build volume as the Kobra 2 and Kobra 2 Pro but the slowest of the three (250 mm/s max, 150 mm/s typical against 300/200 and 500/300), and the only one with a 2.4-inch knob-driven screen instead of a 4.3-inch touchscreen[1][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[5][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Market position: superseded?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[10]
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; 12.1 L[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)485 x 440 x 440 mm stated HWD - footprint about 440 x 440 mm[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)7.3 kg[1]8.3 kg net, 10.6 kg gross[2]
Frame construction & materialNot documentedCNC-machined aluminium extrusion frame[2]
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 structure built from 5 modules[1]Cartesian i3 bed-slinger[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedTwo lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[11]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Not documented"Silent Drive (All Axes)" is all ELEGOO publishes; no driver part number is given[11]
Speed & Acceleration
Max print speed (claimed, mm/s)250 mm/s maximum print speed (Anycubic Lab figure)[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 speed150 mm/s recommended print speed (manufacturer figure)[1]250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[11]
Max acceleration (claimed, mm/s²)Not documented20000 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 nameIntegrated direct extruder[1]Dual-gear direct extruder with 2 fans[11]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedBrass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[11]
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 hot end (manufacturer figure)[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C hotbed temperature ceiling[1]110 C max heated bed temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedPEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[11]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Anycubic LeviQ 2.0 automatic levelling with intelligent Z-offset compensation[1]Manual levelling combined with 121-point auto-levelling; no full-auto calibration on this model[11]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament detection fitted; power-loss resume printing supported[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting design7000 rpm cooling fan (manufacturer 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 published[11]
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][11]
Total rated power drawNot documented310 W rated power, 24 V output[11]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Marlin - Anycubic states it applies "linear propulsion and input shaping functions in Marlin firmware", which makes this one of the few Anycubic machines with a named firmware base rather than the later Kobra OS branding[1][12]Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[11][13]
Connectivity, UI & Camera
Display: size, type, touch?2.4-inch LCD knob screen - not a touchscreen[1]4.3-inch colour capacitive touch screen[11]
On-device UI capabilities (model preview, per-object controls, etc.)Knob-driven UI, redesigned by Anycubic for the Kobra 2 generation[1]Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[11]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveNot documentedLAN 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]
Calibration Routines & QoL
Assembly level & time from unbox to first printFive modules with a gantry frame design, described by Anycubic as easy assembly and low maintenance[1]Not documented
Materials Support
Officially supported filament listPLA, ABS, PETG, TPU (Kobra 2 family list)[6]PLA, TPU, PETG, ABS, ASA, Nylon[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedOperating 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[11]
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.
