| Class | INDUSTRIAL | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | FlashForge Guider 3[1] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[2] |
| Street price (USD; dated snapshot per entry) | Not documented | $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[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Base of a three-model series: Guider 3 (300x250x340), Guider 3 Plus (350x350x600, 250 mm/s, <50 dB, twin sealed 1 kg filament chambers) and Guider 3 Ultra (330x330x600 single-head / 300x330x600 dual-head, two extruders, 350 °C, 7-inch screen, 70 kg). Volumes and extruder counts differ across all three, so series-level spec boxes are unreliable[1][4][5] | 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 Superseded by the V-Core 4.1.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[2][3] |
| Market position: superseded? successor announced? | 3DJake shows it sold out and no longer stocked; the current FlashForge store carries the Guider 3 Ultra[1][5] | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 250 x 340 mm advertised[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][3] |
| Frame construction & material | Fully assembled professional chassis[1] | 30-series aluminium extrusion with printed ABS structural parts[2][3] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed with a heated chamber; 3DJake's table records "Heated chamber: Yes". Chamber temperature not published for this model[1] | Open by default; enclosure panels sold separately[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Not documented | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | TMC2209[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive extruder, single[1] | LDO Orbiter 2.0 direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Phaetus Rapido 2.0 UHF[2] |
| Stock nozzle size & sizes included in box | 0.4, 0.6 and 0.8 mm nozzles available[1] | Not documented |
| Heated Bed & Surface | ||
| Bed surface (material, texture, coating), single/double-sided | Not documented | Keenovo silicone bed heater[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Beacon eddy-current probe[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Nidec 4028 part-cooling fan[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | BigTreeTech Octopus[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not documented | RatOS, Rat Rig's Klipper distribution[3] |
| Connectivity, UI & Camera | ||
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB, Wi-Fi, LAN[1] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | Self-assembly kit; Raspberry Pi and enclosure panels sourced separately[2] |
| Materials Support | ||
| Officially supported filament list | 1.75 mm filament; 3DJake does not publish a per-material list for the base Guider 3[1] | 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.
