| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 2 Plus[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)[1] | Listed on the ELEGOO US store from 27 May 2023 (Shopify publish date)[3] |
| Street price (USD; dated snapshot per entry) | $549.00 on store.anycubic.com, Aug 2026 (the compare-at price of $544.00 is lower than the sale price, which is a store data error rather than a discount)[1] | $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[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Large Kobra 2. Against the small Kobra 2 machines: 320 x 320 x 400 mm build, 13 kg, dual-motor dual Z, 49-point LeviQ 2.0, 8 GB on-board storage and Anycubic APP support - but the bed ceiling drops from 110 C to 90 C, which matters for ABS and ASA. Anycubic's own comparison on the same page is against the older Kobra Plus (350 x 200 x 200 mm, Bowden, 180 mm/s), not against the Kobra 2[1][4][5] | 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[3][2][6][7] |
| Market position: superseded? successor announced? | Not documented | Still 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[8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 400 x 320 x 320 mm stated HWD, i.e. 320 x 320 x 400 mm; Anycubic quotes 40.9 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) | 630 x 605 x 564 mm stated HWD - footprint about 605 x 564 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) | 13 kg[1] | 8.3 kg net, 10.6 kg gross[2] |
| Frame construction & material | Not documented | CNC-machined aluminium extrusion frame[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open 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-backlash | Dual-motor dual Z axis[1] | Two lead screws (the Neptune 4 Plus and Max add two tie rods to the same arrangement)[9] |
| 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[9] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 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][6] |
| Recommended/typical print speed | 300 mm/s typical print speed (manufacturer figure)[1] | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure)[9] |
| Max acceleration (claimed, mm/s²) | Not documented | 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][6][7] |
| 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 name | Direct extruder with double gears[1] | Dual-gear direct extruder with 2 fans[9] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Brass nozzle, 0.4 mm, with a copper and titanium-alloy heat break - the Plus and Max use a titanium-alloy heat break only[9] |
| 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 limit | 90 C hotbed temperature ceiling - lower than the 110 C of the small Kobra 2 machines[1][4] | 110 C max heated bed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | PEI magnetic spring steel plate, 320 x 320 mm[1] | PEI spring steel sheet, now upgraded by ELEGOO to a dual-sided textured PEI + PLA-specific surface[9] |
| 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; no full-auto calibration on this model[9] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted as default[1] | Filament detection fitted; power-loss resume printing supported[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | ELEGOO describes it only as a "Klipper High-Speed Quiet Motherboard" - no board model or MCU published[9] |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Cortex-A7 1.2 GHz processor; 8 GB built-in storage[1] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 115/230 V, 50/60 Hz on the product page; ELEGOO's compare page gives 110-120 / 220-240 VAC 50/60 Hz[2][9] |
| Total rated power draw | Not documented | 310 W rated power, 24 V output[9] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | Klipper (ELEGOO names the system "Klipper" outright for the Neptune 4 series, rather than the ELEGOO OS branding used on the Centauri machines)[9][10] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 4.3-inch colour capacitive touch screen[9] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Anycubic app support (firmware 3.0.5+) for remote monitoring, online slicing and control[1] | Colour capacitive touch UI; ElegooSlicer recommended, with Orca and Cura also supported[9] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | 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][6][7] |
| Materials Support | ||
| Officially supported filament list | PLA, ABS, PETG, TPU (Kobra 2 family list)[4] | PLA, TPU, PETG, ABS, ASA, Nylon[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | 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[9] |
| 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[11] | 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.
