| Property | Anycubic Kobra 2 PlusBEDSLINGER | Rat Rig V-Core 4COREXY |
|---|---|---|
| Identity | ||
| Brand | Anycubic | Rat Rig |
| Class | BEDSLINGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 2 Plus[1] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 31 August 2023 (Shopify publish date)[1] | Not documented |
| 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] | $2,319.99 at Fabreeko for the fully-specified US kit (price includes shipping and duty in the continental USA), Batch 4, checked Aug 2026. 300 mm ABS-parts variant in stock, 400 mm down to one unit. Rat Rig's own base kit is priced separately in EUR[2][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] | Three sizes (300, 400, 500 mm cubes) and three motion configurations: Standard CoreXY, Hybrid CoreXY (+$149.99, adds two motors to Y), and IDEX with two independent toolheads (+$450.00). Superseded by the V-Core 4.1. Raspberry Pi and enclosure panels are not included[2][3] |
| Market position: superseded? successor announced? | Not documented | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables. Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 owners[3] |
| 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] | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 630 x 605 x 564 mm stated HWD - footprint about 605 x 564 mm[1] | Not documented |
| Net weight (kg) | 13 kg[1] | Not documented |
| Frame construction & material | Not documented | 30-series aluminium extrusion with printed ABS structural parts[2][3] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open by default; enclosure panels sold separately[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] | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Dual-motor dual Z axis[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s maximum print speed (Anycubic Lab figure)[1] | Not documented |
| Recommended/typical print speed | 300 mm/s typical print speed (manufacturer figure)[1] | Not documented |
| 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] | LDO Orbiter 2.0 direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Phaetus Rapido 2.0 UHF[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 C nozzle temperature ceiling; 0.4 mm replaceable nozzle[1] | Not documented |
| 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] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | PEI magnetic spring steel plate, 320 x 320 mm[1] | Keenovo silicone bed heater[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] | Beacon eddy-current probe[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted as default[1] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Nidec 4028 part-cooling fan[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | BigTreeTech Octopus[2] |
| 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 |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | RatOS, Rat Rig's Klipper distribution[3] |
| Connectivity, UI & Camera | ||
| 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] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[2] |
| Materials Support | ||
| Officially supported filament list | PLA, ABS, PETG, TPU (Kobra 2 family list)[4] | Not documented |
| 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[6] | Not documented |
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.
