| Property | Anycubic Kobra 4BEDSLINGER | 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 4[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 29 May 2026 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $279.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $379.00 ($320.90 for the EU plug variant)[3] | $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][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Shares its 260 mm cube volume and its exact machine dimensions (455.4 x 445.3 x 461.3 mm) with the Kobra X, so those two cannot be told apart on size. The difference is multicolour: the Kobra X ships with native 4-colour capability, while the Kobra 4 needs an ACE 2 Pro unit for multicolour and drying. The Kobra 4 also has a smaller 3.5-inch screen where the Kobra 3 and S1 use 4.3-inch panels[1][5][6] | 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 Superseded by the V-Core 4.1.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][4] |
| Market position: superseded?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 | Not documented | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[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][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 455.4 x 445.3 x 461.3 mm for the printer; the optional ACE 2 Pro is a separate 368 x 291.5 x 236.5 mm unit[1] | Not documented |
| Net weight (kg) | 9.9 kg for the printer (ACE 2 Pro 3.7 kg); packaged 12.6 kg bare or 17.5 kg as the Combo[1] | Not documented |
| Frame construction & material | Not documented | 30-series aluminium extrusion with printed ABS structural parts[2][4] |
| 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) | Anycubic's table gives the construction as "Gantry system" - a bed-slinger, not CoreXY[1] | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), 300 mm/s the default[1] | Not documented |
| Recommended/typical print speed | 300 mm/s default print speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive ("short distance extrusion")[1] | LDO Orbiter 2.0 direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Hardened-steel nozzle, 0.4 mm standard with 0.25, 0.6 and 0.8 mm optional[1] | Phaetus Rapido 2.0 UHF[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C maximum hotbed temperature on a PEI spring steel build plate[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Keenovo silicone bed heater[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | LeviQ 3.0 49-point auto-levelling with Z-offset; Anycubic claims levelling repeatability under 0.02 mm and states no manual compensation is needed[1] | Beacon eddy-current probe[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, entanglement detection and power-loss resume[1] | Not documented |
| Multi-material/multi-color capability or official upgrade path | Multicolour and active drying both require the separate ACE 2 Pro unit; Anycubic quotes 4 independent brushless feed motors in that unit[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] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS with pressure advance and flow calibration; a built-in accelerometer drives vibration compensation[1] | RatOS, Rat Rig's Klipper distribution[4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch capacitive touchscreen - smaller than the 4.3-inch panels on the Kobra 3 and S1 series[1][6][7] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Anycubic Slicer, the Anycubic app and USB; AI spaghetti detection and object skip supported[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Anycubic Slicer and the Anycubic app[1] | Not documented |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Standard HD camera fitted, 720p[1] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Anycubic claims assembly and first print within 15 minutes[1] | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[2] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, TPU 95A - and Anycubic notes TPU 95A cannot be used through the ACE 2 Pro[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | 48 dB or less in standard mode and 45 dB or less in silent print mode - manufacturer figures with no distance or method stated[1] | 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[8] | Not documented |
| Independently Measured Performance | ||
| Benchmark print times (source + settings) | Anycubic claims a 14-minute Benchy - a manufacturer figure with no slicer settings published, not an independent measurement[1] | 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.
