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 SV07[2][3]
Street price (USD; dated snapshot per entry)Not documented$299 at 3D Printers Online Store but Out of Stock, checked Aug 2026. Sovol's own comparison article quotes $259. No in-stock listing found[3][4]
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 of a two-model pair with the SV07 Plus (300x300x350, 600 W MeanWell PSU, 25-point levelling, adds USB Type-C). The SV07 has a 350 W MeanWell PSU. Both are quoted by Sovol at 500 mm/s and 300 °C, so PSU wattage and build volume are the reliable discriminators[4][3][5]
Market position: superseded?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]Delisted by Sovol; not present in the current 3D-printer collection. 3DJake shows it sold out and no longer stocked[6][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 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][3]
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]460 x 457 x 625 mm[3]
Net weight (kg)Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[1]9.8 kg machine weight; 12.9 kg boxed[3]
Frame construction & material30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[1]Open frame, supplied as an assembly kit[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame in the base kit[1]Open frame; 3DJake records "Heated chamber: No"[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 documentedConflicting manufacturer figures: Sovol's own comparison says up to 500 mm/s, 3DJake's feature text says up to 250 mm/s, and the retailer listing gives a 250-500 mm/s range. 500 is the headline claim, 250 the working figure[4][2][3]
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 nameFull-metal skeleton toolhead, new in the 4.1[1]All-metal dual-gear direct drive with a planetary gearbox[2][4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedAll-metal hotend to 300 °C[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][3][4]
Stock nozzle size & sizes included in box0.4 mm hardened steel and 0.6 mm included[1]Not documented
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[1]<=100 °C claimed[3]
Bed surface (material, texture, coating), single/double-sidedNot documentedReversible PEI build plate[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedAutomatic bed levelling over 25 points; probe technology not stated[2]
Mesh grid size (probe point count — firmware evidence)Not documented25 points (manufacturer claim)[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designImproved part cooling, listed by Rat Rig as one of the 4.1 changes[1]Triple-fan cooling (Sovol's description; fan sizes and duct design not published)[2][4]
Electronics & Power
PSU (brand, wattage, rail voltage)Not documented350 W MeanWell, 24 V, 115/230 V AC input[4][3]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)RatOS 2.1 (Rat Rig's Klipper distribution)[1]Klipper[2][4]
Connectivity, UI & Camera
Display: size, type, touch?Not documented5-inch touchscreen (Sovol markets it as a "5-inch HD Klipper screen")[2][4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveNot documentedWi-Fi and USB Type-C[2][4][3]
Calibration Routines & QoL
Assembly level & time from unbox to first printSelf-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[1]Not documented
Materials Support
Officially supported filament listPLA, 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, ABS, wood-filled; Sovol also lists carbon fibre[3][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.
