| 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] | Voron 2.4, current revision R2, kits shipping as Rev D and Rev D+. Sold as "Voron 2.4 R2 (Rev D+) 3D Printer Kit by LDO"[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] | $1,399.99 for the LDO Rev D+ kit at Fabreeko (300 mm and 350 mm are the same price), on pre-order with a mid-September estimate, checked Aug 2026. Fabreeko's live feed shows the base 2.4 kit listing at $1,299.99 and available. 3DJake lists an LDO 350 RevD kit but will not ship to the US[2][5][6] |
| 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 Superseded by the V-Core 4.1.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] | Sizes 250, 300 and 350 mm; LDO ships Rev D and Rev D+. Colours black, space grey, blue. Do not confuse with the Trident: the 2.4 lifts the whole gantry on four belted Z motors, the Trident lifts the bed on three screws. The Rev D+ kit includes a Raspberry Pi 4B; the older 3DJake-listed RevD kit explicitly does not include a Pi[2][3][6][7] |
| Market position: superseded?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 | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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 300 mm or 350 x 350 x 350 mm. Sortable value is the 350 mm kit[2][3][6] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][4] | Blind-joint aluminium-extrusion frame with a complete panel set; stainless-steel linear rails throughout[3][6] |
| Enclosure: open / enclosed; panel material; door/lid | Open by default; enclosure panels sold separately[1] | Enclosed by the supplied panel set. A Nevermore Micro V5 internal circulation filter is included in the LDO kit[6] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[1] | CoreXY on linear rails, with a belted flying gantry on four Z motors[3][2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209[1] | LDO Leviathan board: 5 x TMC2209 plus 2 x TMC5160 HV-capable drivers, ready for 48 V upgrades[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | Clockwork 2 with a Bondtech BMG / Integrated Drive Gear Assembly, in a Stealthburner toolhead[2][3][6] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | E3D Revo Voron (24 V), all-metal, high-flow variant in the Rev D+ kit, with a 60 W heater; upgradeable to a Phaetus Rapido HF for $9.99[2][3][6] |
| Heater cartridge power (W) | Not documented | 60 W (E3D Revo High Flow heater)[2] |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | Cast 5083 aluminium plate with a magnetic base and a powder-coated PEI sheet; LDO silicone bed heater with edge-to-edge heating[3][2][6] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | Omron inductive probe supplied; Klicky-mod parts included. Voron Tap is available as an add-on rather than standard[2][3] |
| 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] | LDO x Voron Leviathan mainboard (replacing the earlier BTT Octopus), plus a Nitehawk SB USB toolhead PCB[3][2][6] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[4] | Klipper, hosted on a Raspberry Pi 4B (included in the Fabreeko Rev D+ kit, not in the older 3DJake RevD kit)[2][3][6] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | Not documented | 4.3-inch touchscreen included in the LDO kit[6] |
| LED chamber/toolhead lighting | Not documented | COB LED strips included[2][6] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[1] | Self-assembly kit; some parts must be printed by the user, and the LDO kit supplies pre-cut, pre-crimped cables and a heat-set insert soldering tip[6] |
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.
