| Property | Creality K2COREXY | ELEGOO Centauri 2 ComboCOREXY |
|---|---|---|
| Identity | ||
| Brand | Creality | ELEGOO |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Creality K2[1] | ELEGOO Centauri 2 Combo - the Centauri 2 sold with the CANVAS multicolour unit[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Smallest of three K2 machines that share a product page. K2: 260 mm cube, no chamber heating, 100 C bed, 300 C nozzle, 8 GB storage, one air filter, one auxiliary cooling fan, 720p camera, no RFID reader, no Ethernet. K2 Pro: 300 mm cube, 60 C chamber, 110 C bed, RFID, Ethernet, 32 GB. K2 Plus: 350 mm cube, 350 C nozzle, 120 C bed, 30000 mm/s2, dual air filters, auto belt tensioning, 1080p camera, dual-band Wi-Fi. A K2 SE also exists as a separate model[1] | Same printer as the bare Centauri 2 for every motion, hotend, bed and electronics figure; what the Combo adds is 4-colour CANVAS printing, RFID filament detection, auto refill and auto tangle detection, and what it costs is bench space - 500 x 480 x 586 mm and 15.5 kg against 398 x 404 x 490 mm and 13.7 kg. Camera, LED lighting and air filter remain optional expansions on both[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 260 x 260 x 260 mm[1] | 256 x 256 x 256 mm; printing platform 260 x 260 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 404 x 436 x 545 mm[1] | 500 x 480 x 586 mm with the CANVAS unit fitted[2] |
| Net weight (kg) | 18.3 kg[1] | 15.5 kg net, 19 kg gross[2] |
| Frame construction & material | Not documented | Rigid aluminium frame (Centauri 2 platform)[2] |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed, but with no chamber temperature control - Creality's table gives a max chamber temperature for the K2 Pro and K2 Plus and a dash for the K2. One air filter fitted[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - Creality groups the K2 series with its CoreXY flagships and quotes 600 mm/s with step-servo motors on the X and Y axes[1] | CoreXY with dual 4260 stepper motors[2] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Three lead screws with three linear guide rods[2] |
| Belts (type, width, e.g. Gates?) | Manual belt tensioning (the K2 Plus is auto-adjusted)[1] | Not documented |
| Stepper motors (frame size, step angle, brand if known) | Step-servo motors on the X and Y axes and the extruder (the K2 Plus adds them on Z)[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s max printing speed (manufacturer claim)[1] | 500 mm/s or less, recommended 250 mm/s[2] |
| Recommended/typical print speed | Not documented | 250 mm/s recommended printing speed[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 max acceleration (manufacturer claim)[1] | 20000 mm/s2 maximum acceleration; default 10000 mm/s2[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Dual-gear direct extruder with one fan[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Not documented | Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[2] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | 350 C claimed max nozzle temperature[2] |
| Heater cartridge power (W) | 70 W rated hotend power[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature - the lowest in the K2 family[1] | 110 C max heated bed temperature at 25 C ambient[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Smart auto levelling fitted; unlike the K2 Pro and Plus there is no nozzle AI camera, so there is no automatic flow-rate calibration[1] | 121-point auto-levelling plus partial bed levelling[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out sensor, clog detection, auto tangle detection, RFID filament detection, auto refill, auto filament unloading and power-loss recovery[2] |
| Multi-material/multi-color capability or official upgrade path | Not documented | CANVAS four-colour printing with RFID filament identification and automatic refill - the defining difference from the bare Centauri 2[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | One auxiliary cooling fan and one air filter[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | "Powerful Self-Developed Motherboard"[2] |
| Total rated power draw | Not documented | 1100 W at 220 V, 350 W at 110 V rated[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Creality OS, a Klipper derivative. Creality publishes the K2 firmware source as CrealityOfficial/K2_Series_Klipper on GitHub under GPL-3.0, last pushed March 2026[3][4][1] | ELEGOO OS; ElegooSlicer recommended[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4-inch touchscreen[1] | 5-inch colour capacitive touch screen[2] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touch UI with alarm sounds; no built-in RFID reader[1] | Colour touch UI; STL, OBJ, 3MF and STEP input[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi 2.4 GHz, USB drive and a Creality 485 port; no Ethernet. 8 GB eMMC storage[1] | USB and Wi-Fi[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | One chamber camera, 720p at 30 fps[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, PET, ABS, PLA-CF - a shorter list than the K2 Pro and Plus, which add ASA, PA-CF and PPA-CF[1] | Ideal: PLA, PETG, PLA-CF, TPU. Not recommended: ABS/ABS-CF, ASA/ASA-CF, PET/PET-CF, PETG-CF, PA/PA-CF, PC[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not verified directly. Creality publishes the K2-series firmware as CrealityOfficial/K2_Series_Klipper (GPL-3.0); upstream Klipper ships the verify_heater thermal-runaway check, but whether the stock configuration enables it was not checked here[3][4] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Creality's US store states "Up to 12-Month Warranty", a 14-day return and refund window and "Lifetime Customer Support" on its printer product pages. The "up to" wording means the term is not uniform across parts[5] | 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[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.
