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 Plus[2][3]
Street price (USD; dated snapshot per entry)Not documented$199 at 3D Printers Online Store, reduced from $379, but Out of Stock, checked Aug 2026. Sovol's own comparison quotes $259 sale / $309-379 regular[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]Large-format version of the SV07. Distinguishers: 300x300x350 mm vs 220x220x250, 600 W MeanWell vs 350 W, 25-point levelling, and USB Type-C added. Both are quoted at 500 mm/s and 300 °C. Note Sovol's own comparison table gives 300x300x350 while some listings write 300x300x340[3][2]
Market position: superseded?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[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[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documented25-point automatic levelling; probe technology not stated[3]
Mesh grid size (probe point count — firmware evidence)Not documented25 points (manufacturer claim)[3]
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]Enhanced triple cooling (Sovol's wording; no fan detail published)[3]

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[2][3]

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.
