| Property | Rat Rig V-Core 4COREXY | 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, sold in the US as "RatRig V-Core 4 3D Printer Kit"[1] | Sovol SV06[2] |
| 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][3] | Not documented |
| 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 Superseded by the V-Core 4.1.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][3] | 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][4][5] |
| Market position: superseded?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 | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[3] | 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 Superseded by the SV06 ACE[6][2] |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][3] | 220 x 220 x 250 mm advertised[2] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][3] | Open i3-style frame, supplied as an assembly kit[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open by default; enclosure panels sold separately[1] | Open frame, no enclosure[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] |
| 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?) | TMC2209[1] | TMC2209 drivers on a 32-bit silent board (Sovol description, not verified against a board photo)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | All-metal direct-drive extruder with planetary gear reduction[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | All-metal hotend rated to 300 °C. MK8-style nozzle[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 300 °C claimed[2] |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | Flexible PEI build surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | 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 | Nidec 4028 part-cooling fan[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | BigTreeTech Octopus[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[3] | 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; 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 | Resume-after-power-loss supported; mechanism not published[2] |
| Materials Support | ||
| Officially supported filament list | Not documented | 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.
