| Property | Rat Rig V-Core 4.1COREXY | 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 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[1] | Sovol SV06 Plus ACE 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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, 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] | 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][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| Market position: superseded?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] | 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] | 300 x 300 x 350 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] | 510 x 575 x 710 mm including screen and filament holder[2] |
| 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; Sovol publishes no frame-material breakdown[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] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 500 mm/s maximum (manufacturer claim)[2] |
| 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] | 15,000 mm/s2 maximum (manufacturer claim)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Full-metal skeleton toolhead, new in the 4.1[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?) | Not documented | 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) | 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] | 100 °C claimed[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Double-sided textured PEI plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | 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 | 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 | Rockchip RK3308 ("3308 chip"), 512 MB RAM, 8 GB eMMC[2] |

| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS 2.1 (Rat Rig's Klipper distribution)[1] | 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; 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 | None. Sovol's own spec table states "Power Loss Recovery: None" for this model[2] |

| 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] | 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.
