| Property | Rat Rig V-Core 4COREXY | Sovol SV06 Plus ACEBEDSLINGER |
|---|---|---|
| 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 Plus ACE 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] | $299.00 on sovol3d.com against a $349.00 compare-at price, in stock and shipping from US/EU/CA/AU/UK/CN warehouses, 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 Superseded by the V-Core 4.1.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] | Larger sibling of the SV06 ACE ($239, 220x220x250). Differs from the non-ACE SV06 Plus by Z height (350 vs 340 mm), Klipper on an RK3308, ceramic-plate hotend, 4.3-inch capacitive touchscreen and a camera. Notably it has NO power-loss recovery, which the older SV06 did have[2][3][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| Market position: superseded?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 | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[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] | 300 x 300 x 350 mm advertised[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 510 x 575 x 710 mm including screen and filament holder[2] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][4] | Open i3-style frame; Sovol publishes no frame-material breakdown[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] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209[1] | Not documented |
| Speed & Acceleration | ||

| Max acceleration (claimed, mm/s²) | Not documented | 15,000 mm/s2 maximum (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | Planetary double-gear direct drive, 1:7.5 reduction[2] |
| Gear ratio & drive gear material | Not documented | 1:7.5[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | Ceramic heating plate hotend; 0.4 mm nozzle included, 0.6 and 0.8 mm optional[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | <=300 °C claimed[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 100 °C claimed[2] |
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | Double-sided textured PEI plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | Automatic levelling (Sovol calls the ACE upgrade an added automatic levelling function); probe technology not named on this page[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out sensor fitted; type and location not published[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 |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | Rockchip RK3308 ("3308 chip"), 512 MB RAM, 8 GB eMMC[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 500 W / 24 V, 100-240 VAC 50/60 Hz[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[4] | Klipper. Sovol does not publish the fork or version on the product page. OTA updates supported[2] |

| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Not documented | Wi-Fi 2.4 GHz only, WPA2 only (WPA3 explicitly not supported)[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera, default 640x480, maximum 1280x720 (Sovol writes it as 1080x720P)[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 | None. Sovol's own spec table states "Power Loss Recovery: None" for this model[2] |
| Materials Support | ||
| Officially supported filament list | Not documented | PLA, PETG, TPU, PVA[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.
