| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Centauri Carbon[1] | Rat Rig V-Core 4, sold in the US as "RatRig V-Core 4 3D Printer Kit"[2] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 17 February 2025 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $419.99 on us.elegoo.com, Aug 2026, with the compare-at price also $419.99 (no discount running)[3] | $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][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Superseded by the Centauri Carbon 2, which raises the nozzle ceiling to 350 C and swaps the nano mineral crystal filter for a HEPA plus coconut-shell carbon stack, adds clog detection, a smart exhaust grille and part-cooling-fan drop detection. The non-carbon Centauri and Centauri 2 are open-frame-oriented machines with a different filament list. Machine size 398 x 404 x 490 mm is shared with the Centauri 2, so body dimensions alone will not identify the model[5][6][1] | 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 Superseded by the V-Core 4.1.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][4] |
| Market position: superseded? successor announced? | Superseded within ELEGOO's own line-up: the US store's Centauri section in Aug 2026 lists the Centauri Carbon 2 Combo, Centauri 2 Combo, Centauri Carbon 2 and an emoji collaboration edition[7] | Superseded by the V-Core 4.1, which adds a steel X gantry, a full-metal toolhead, improved part cooling, 8 mm beds on the 400 and 500 sizes and pre-made cables.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] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 256 x 256 x 256 mm; printing platform 260 x 260 mm[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][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 398 x 404 x 490 mm[1] | Not documented |
| Net weight (kg) | 17.5 kg net, 21 kg gross[1] | Not documented |
| Frame construction & material | Integrated die-cast aluminium construction, which ELEGOO credits for reduced vibration at speed[1] | 30-series aluminium extrusion with printed ABS structural parts[2][4] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a tempered glass door and top cover; a nano mineral crystal air filter, an auxiliary part-cooling fan and a chamber temperature regulator fan are fitted[1] | Open by default; enclosure panels sold separately[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1] | CoreXY, or Hybrid CoreXY, or Hybrid CoreXY IDEX depending on the configuration ordered[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Three lead screws with three linear guide rods[1] | Not documented |
| Belts (type, width, e.g. Gates?) | Semi-automatic belt tensioner[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)" is all that is published; no driver part number is given[1] | TMC2209[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s or less, with 250 mm/s given by ELEGOO as the recommended speed[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed (manufacturer figure)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration; default acceleration 10000 mm/s2[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | 32 mm3/s claimed flow rate (manufacturer figure; no test conditions published)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with one fan[1] | LDO Orbiter 2.0 direct-drive extruder[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass-hardened steel nozzle, 0.4 mm, with a titanium-alloy heat break; a heatbed nozzle wiper cleans it before each print[1] | Phaetus Rapido 2.0 UHF[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 320 C claimed max nozzle temperature (the Centauri Carbon 2 raises this to 350 C)[1][5] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C max heated bed temperature at 25 C ambient[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided spring steel sheet - textured PEI on one face, a PLA-specific surface on the other[1] | Keenovo silicone bed heater[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 121-point auto-levelling with full-auto calibration[1] | Beacon eddy-current probe[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor, auto filament unloading, power-loss recovery and fan self-check; no clog detection on this model (the Centauri Carbon 2 adds it)[1][5] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Part cooling plus an auxiliary part-cooling fan and a chamber temperature regulator fan, with real-time fan self-checks[1] | Nidec 4028 part-cooling fan[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | ELEGOO describes it only as a "Powerful Self-Developed Motherboard"; no board model or MCU is published[1] | BigTreeTech Octopus[2] |
| Total rated power draw | 1100 W at 220 V, 350 W at 110 V rated; 24 V output; 100-240 VAC input[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | ELEGOO OS with OTA updates; 8 GB of on-board storage. ElegooSlicer recommended, with Orca and Cura supported[1] | RatOS, Rat Rig's Klipper distribution[4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour touch UI; LED chamber lighting fitted; OTA firmware updates[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB and dual-band Wi-Fi for LAN transfers[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 | Carbon/glass fibre reinforced filaments, PLA, PETG, ABS, ASA, TPU, PET, PC, PA[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 55 dB or less - a manufacturer figure with no distance or method stated, so not comparable with an independently measured dB reading[1] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[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.
