ClassBEDSLINGERCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 2[1]Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 15 May 2023 (Shopify publish date)[1]Not documented
Street price (USD; dated snapshot per entry)$169.00 on store.anycubic.com, Aug 2026, against a compare-at price of $279.00 - the cheapest machine in this file[1]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Base model of a five-way family that is easy to confuse. All of Kobra 2, Kobra 2 Neo and Kobra 2 Pro share the same 220 x 220 x 250 mm build volume, but their speed ceilings differ: Neo 250 mm/s max / 150 typical, Kobra 2 300 / 200, Kobra 2 Pro 500 / 300. The Plus (320 x 320 x 400 mm) and Max (420 x 420 x 500 mm) are bigger but drop the bed ceiling to 90 C where the three small ones reach 110 C. Anycubic's own note: Kobra 2 firmware must be at V3.0.6 or above for the quoted speed[1][3][4][5][6]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[2]
Market position: superseded? successor announced?Not documentedCurrent revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 220 x 220 mm stated HWD, i.e. 220 x 220 x 250 mm in X x Y x Z; Anycubic quotes 12.1 L[1]300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)486 x 440 x 435 mm stated as HWD, so the desk footprint is about 440 x 435 mm and the height is 486 mm[1]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[2]
Net weight (kg)8.4 kg[1]Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[2]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger with a gantry frame; Anycubic describes double metal spindles with SG15 bearings on the moving axes[1]CoreXY; Hybrid CoreXY and IDEX are configuration options[2]

Recommended/typical print speed200 mm/s recommended print speed (manufacturer figure) - the number to plan around, not the 300 mm/s headline[1]Not documented
Max acceleration (claimed, mm/s²)3000 mm/s2 acceleration (manufacturer figure) - modest next to the 20000 mm/s2 of the current Kobra generation[1][7]Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[2]
Extruder

Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)260 C nozzle temperature ceiling; 0.4 mm replaceable nozzle[1]350 °C maximum nozzle temperature (manufacturer claim)[2]
Heater cartridge power (W)60 W hotend heater (Anycubic states "upgraded extruder power reaches up to 60 watts")[1]Not documented
Stock nozzle size & sizes included in boxNot documented0.4 mm hardened steel and 0.6 mm included[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C hotbed temperature ceiling[1]120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Anycubic LeviQ 2.0 automatic levelling with smart Z-offset and a user-adjustable Z compensation value[1]Not documented

Calibration Routines & QoL
Assembly level & time from unbox to first printModular assembly - Anycubic states 5 pieces in about 10 minutes[1]Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[2]

Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[8]Not documented

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.
