| Property | Rat Rig V-Core 4COREXY | Sovol SV07BEDSLINGER |
|---|---|---|
| Identity | ||
| Brand | Rat Rig | Sovol |
| Class | COREXY | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[1] | Sovol SV07[2][3] |
| Street price (USD; dated snapshot per entry) | $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[1][4] | $299 at 3D Printers Online Store but Out of Stock, checked Aug 2026. Sovol's own comparison article quotes $259. No in-stock listing found[3][5] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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 Superseded by the V-Core 4.1.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[1][4] | Base of a two-model pair with the SV07 Plus (300x300x350, 600 W MeanWell PSU, 25-point levelling, adds USB Type-C). The SV07 has a 350 W MeanWell PSU. Both are quoted by Sovol at 500 mm/s and 300 °C, so PSU wattage and build volume are the reliable discriminators[5][3][6] |
| Market position: superseded? successor announced? | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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] | Delisted by Sovol; not present in the current 3D-printer collection. 3DJake shows it sold out and no longer stocked[7][2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[1][4] | 220 x 220 x 250 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 460 x 457 x 625 mm[3] |
| Net weight (kg) | Not documented | 9.8 kg machine weight; 12.9 kg boxed[3] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][4] | Open frame, supplied as an assembly kit[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open by default; enclosure panels sold separately[1] | Open frame; 3DJake records "Heated chamber: No"[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[1] | Cartesian i3 bedslinger[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | Conflicting manufacturer figures: Sovol's own comparison says up to 500 mm/s, 3DJake's feature text says up to 250 mm/s, and the retailer listing gives a 250-500 mm/s range. 500 is the headline claim, 250 the working figure[5][2][3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | All-metal dual-gear direct drive with a planetary gearbox[2][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | All-metal hotend to 300 °C[2][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=300 °C claimed[2][3][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=100 °C claimed[3] |
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | Reversible PEI build plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | Automatic bed levelling over 25 points; probe technology not stated[2] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 25 points (manufacturer claim)[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Nidec 4028 part-cooling fan[1] | Triple-fan cooling (Sovol's description; fan sizes and duct design not published)[2][5] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | BigTreeTech Octopus[1] | Not documented |
| PSU (brand, wattage, rail voltage) | Not documented | 350 W MeanWell, 24 V, 115/230 V AC input[5][3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[4] | Klipper[2][5] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 5-inch touchscreen (Sovol markets it as a "5-inch HD Klipper screen")[2][5] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | Wi-Fi and USB Type-C[2][5][3] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | Not documented | PLA, PETG, TPU, ABS, wood-filled; Sovol also lists carbon fibre[3][5] |
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.
