| Property | Rat Rig V-Core 4COREXY | Sovol SV08 MaxCOREXY |
|---|---|---|
| Identity | ||
| Brand | Rat Rig | Sovol |
| Class | COREXY | COREXY |
| 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 SV08 Max 3D Printer[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] | $1,099.00 on sovol3d.com against a $1,299.00 compare-at price (15% off), in stock, checked Aug 2026[2][3] |
| 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 Superseded by the V-Core 4.1.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] | Much larger sibling of the SV08. Differences that matter in a spec box: 500x500x500 vs 350x350x345, 50 vs 30 mm3/s, TMC5160 XY drivers vs TMC2209, CAN bus, HDMI output, dual 0.4 mm nozzles in the box, and a separately sold chamber-heating module. A chamber heating module for the SV08 Max is listed at $69[2][5][6][3] |
| Market position: superseded?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 | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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] | Not documented |
| 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] | 500 x 500 x 500 mm advertised[2][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 700 x 710 x 750 mm excluding the spool holder. Shipping cartons: 810 x 820 x 360 mm plus a 775 x 728 x 155 mm enclosure-kit box[2][5] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][4] | Aluminium-extrusion CoreXY frame supplied as a kit; Sovol ships it in two cartons, one of which is an enclosure kit[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open by default; enclosure panels sold separately[1] | Enclosure kit shipped with the machine (separate carton). A chamber-heating module is sold separately at $69[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[1] | CoreXY[2][5] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209[1] | Z axis 4 x TMC2209; A axis 1 x TMC5160; B axis 1 x TMC5160. Toolhead communication over CAN bus[2][5] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 700 mm/s maximum (manufacturer claim)[2][5] |
| Max acceleration (claimed, mm/s²) | Not documented | 40,000 mm/s2 maximum (manufacturer claim)[2][5] |
| Max volumetric flow claimed (mm³/s) | Not documented | 50 mm3/s maximum (manufacturer claim)[2][5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | Direct drive with auxiliary (assisted) filament feeding[2][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | Ceramic heater. Two 0.4 mm nozzles supplied as standard; 0.4/0.6/0.8 mm optional[2][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=300 °C claimed[2][5] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | <=100 °C claimed[2][5] |
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | Not stated on the SV08 Max page; the SV08 family uses an inductive sensor plus pressure sensor[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament runout detection plus filament tangle/clog detection. Sovol does not describe the tangle or clog mechanism[2][5] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Nidec 4028 part-cooling fan[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | BigTreeTech Octopus[1] | Not documented |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | 1 GB RAM (512 MB + 512 MB), 8 GB eMMC[2][5] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[4] | Klipper (3DJake's table renders it as "Clipper"). OrcaSlicer is the supported slicer[2][5] |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | USB, Wi-Fi 2.4 GHz and 5 GHz, HDMI, Ethernet[2][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[1] | Not documented |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss resume printing supported; mechanism not published[2][5] |
| Materials Support | ||
| Officially supported filament list | Not documented | 1.75 mm filament; Sovol does not publish a per-material list on this page[2][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.
