| Property | Rat Rig V-Core 4.1COREXY | Sovol SV06BEDSLINGER |
|---|---|---|
| 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 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[1] | Sovol SV06[2] |
| 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] | Base model of a four-way family: SV06 (220x220x250, Marlin-era silent board), SV06 Plus (300x300x340), SV06 ACE and SV06 Plus ACE (both Klipper, ceramic hotend, camera, 4.3-inch touchscreen). ACE specs must not be applied to the non-ACE machines[2][3][4] |
| Market position: superseded?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] | No longer listed on Sovol's own store: the current 3D-printer collection contains only SV08, SV08 Max, Zero, SV06 ACE and SV06 Plus ACE. 3DJake also shows it sold out and delisted. Superseded by the SV06 ACE[5][2] |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] | 220 x 220 x 250 mm advertised[2] |
| 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] | Not documented |
| 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] | Open i3-style frame, supplied as an assembly kit[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame in the base kit[1] | Open frame, no enclosure[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY; Hybrid CoreXY and IDEX are configuration options[1] | Cartesian i3 bedslinger[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual Z-axis motors[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209 drivers on a 32-bit silent board (Sovol description, not verified against a board photo)[2] |
| Speed & Acceleration | ||
| 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] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Full-metal skeleton toolhead, new in the 4.1[1] | All-metal direct-drive extruder with planetary gear reduction[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | All-metal hotend rated to 300 °C. MK8-style nozzle[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 350 °C maximum nozzle temperature (manufacturer claim)[1] | 300 °C claimed[2] |
| 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] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Flexible PEI build surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic levelling over 25 points; probe technology not stated on the listing[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 | Improved part cooling, listed by Rat Rig as one of the 4.1 changes[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS 2.1 (Rat Rig's Klipper distribution)[1] | Not documented |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | USB connection; micro-SD card. No Wi-Fi[2] |
| 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 | Resume-after-power-loss supported; mechanism not published[2] |
| 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 for this model beyond the 300 °C hotend rating[2] |
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.
