| 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 0.2, current revision R1. Sold under kit vendors' names: "Voron V0.2-S1 (R1) 3D Printer Kit by LDO & HoneyBadger", "Voron 0.2 R1 Latest Version CoreXY 3D Printer Kit" (Formbot)[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] | There is no single price: Voron is an open design and kits come from several vendors. Formbot's kit is $328.06 (was $349.00, 6% off), in stock, checked Aug 2026. The LDO & HoneyBadger V0.2-S1 kit is $639.99 but sold out. Neither figure includes printed parts unless the option is selected[2][3] |
| 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 Superseded by the V-Core 4.1.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] | Two things get conflated. First, revision: R1 is the current one, adding a filament-runout sensor, MR85 bearings and fastener changes. Second, kit vendor: the LDO/HoneyBadger S1 kit ships an SKR Pico, E3D Revo, HoneyBadger dual-sided PEI/CF bed and 200 W supply, while the Formbot kit ships a TZ V6 or Dragon hotend and a 150 W supply, so hotend and PSU specs are vendor-specific, not model-specific. Printed parts are an extra on both[2][3] |
| Market position: superseded?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 | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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] | 120 x 120 x 120 mm[2][3] |
| Frame construction & material | 30-series aluminium extrusion with printed ABS structural parts[1][4] | Aluminium-extrusion CoreXY frame with acrylic panels (LDO kit); the LDO/HoneyBadger build uses a 100 mm top hat. X axis on a genuine HIWIN rail, Y and Z on HoneyBadger stainless rails[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open by default; enclosure panels sold separately[1] | Enclosed by acrylic panels in the LDO kit[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[1] | CoreXY with the build plate moving in Z[2][3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Genuine HIWIN linear rail on X in the LDO kit[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | TMC2209[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 250 mm/s max print speed, 300 mm/s max travel (Formbot kit listing). This is a kit-vendor figure, not a Voron Design specification[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | LDO Orbiter 2.0 direct-drive extruder[1] | Direct drive in a Mini Stealthburner toolhead with a picobilical board and umbilical cable (LDO kit)[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Phaetus Rapido 2.0 UHF[1] | Kit-dependent: E3D Revo (Voron edition) in the LDO kit; TZ V6, Dragon standard-flow or Dragon high-flow in the Formbot kit[2][3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 300 °C on the Formbot kit listing. The LDO kit's E3D Revo has its own limit, not stated on the listing[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 110 °C (Formbot kit listing)[3] |
| Bed surface (material, texture, coating), single/double-sided | Keenovo silicone bed heater[1] | HoneyBadger dual-sided P-series plate in the LDO kit: smooth black PEI on one face, carbon fibre on the other, on a Kirigami mount with an edge-to-edge polyimide film heater[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Beacon eddy-current probe[1] | Not documented |
| 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] | Kit-dependent. LDO kit: SKR Pico (LDO Edition) with a Raspberry Pi 4B as host[2] |
| PSU (brand, wattage, rail voltage) | Not documented | 200 W (LDO kit) or 150 W (Formbot kit)[2][3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | RatOS, Rat Rig's Klipper distribution[4] | Klipper[2] |
| 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. Printed parts are not included in the LDO kit (sourced separately, e.g. through Voron's Print It Forward); the Formbot kit offers them as an option[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.
