| Property | Rat Rig V-Core 4.1COREXY | 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 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[1] | Sovol SV08 Max 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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, all at the same base-kit price. Acceleration is the size-dependent figure and the one most often mis-quoted: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm. IDEX is a configuration option and changes the usable area per toolhead (copy mode 150x150x300 at the 300 size, mirror mode 95x95x300). Base kit excludes electronics. Rat Rig prices the base kit only in EUR (EUR 873.90 on sale from EUR 971.00, Aug 2026); no USD list price is published, so no USD street price is recorded here[1] | 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][4][5][3] |
| Market position: superseded? successor announced? | Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[1] | 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] | 500 x 500 x 500 mm advertised[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 623.2 x 583 x 785 mm (300); 723.2 x 683 x 885 mm (400); 823.2 x 783 x 985 mm (500). Sortable value is the 300 mm kit[1] | 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][4] |
| Net weight (kg) | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[1] | Not documented |
| Frame construction & material | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[1] | 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 frame in the base kit[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; Hybrid CoreXY and IDEX are configuration options[1] | CoreXY[2][4] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Z axis 4 x TMC2209; A axis 1 x TMC5160; B axis 1 x TMC5160. Toolhead communication over CAN bus[2][4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 700 mm/s maximum (manufacturer claim)[2][4] |
| Max acceleration (claimed, mm/s²) | Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[1] | 40,000 mm/s2 maximum (manufacturer claim)[2][4] |
| Max volumetric flow claimed (mm³/s) | Not documented | 50 mm3/s maximum (manufacturer claim)[2][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Full-metal skeleton toolhead, new in the 4.1[1] | Direct drive with auxiliary (assisted) filament feeding[2][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Ceramic heater. Two 0.4 mm nozzles supplied as standard; 0.4/0.6/0.8 mm optional[2][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum nozzle temperature (manufacturer claim)[1] | <=300 °C claimed[2][4] |
| Stock nozzle size & sizes included in box | 0.4 mm hardened steel and 0.6 mm included[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[1] | <=100 °C claimed[2][4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | 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][4] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Improved part cooling, listed by Rat Rig as one of the 4.1 changes[1] | Not documented |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | 1 GB RAM (512 MB + 512 MB), 8 GB eMMC[2][4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS 2.1 (Rat Rig's Klipper distribution)[1] | Klipper (3DJake's table renders it as "Clipper"). OrcaSlicer is the supported slicer[2][4] |
| 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][4] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[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][4] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, ABS, ASA, TPU, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[1] | 1.75 mm filament; Sovol does not publish a per-material list on this page[2][4] |
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.
