Identity

ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1[1]ELEGOO Centauri 2 Combo - the Centauri 2 sold with the CANVAS multicolour unit[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 for the EU plug variant)[3]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][4]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 usable250 x 250 x 250 mm[1]256 x 256 x 256 mm; printing platform 260 x 260 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)400 x 410 x 490 mm[1]500 x 480 x 586 mm with the CANVAS unit fitted[2]
Net weight (kg)9.37 kg net, 20.2 kg packaged[1]15.5 kg net, 19 kg gross[2]
Frame construction & materialNot documentedRigid aluminium frame (Centauri 2 platform)[2]
Enclosure: open / enclosed; panel material; door/lidFully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][4]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (stated outright in Anycubic's specification table)[1]CoreXY with dual 4260 stepper motors[2]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedThree lead screws with three linear guide rods[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]500 mm/s or less, recommended 250 mm/s[2]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]250 mm/s recommended printing speed[2]
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1]20000 mm/s2 maximum acceleration; default 10000 mm/s2[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Dual-gear direct extruder with one fan[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1]Brass-hardened steel nozzle, 0.4 mm, titanium-alloy heat break[2]
Max nozzle temp claimed AND firmware max temp limit (both values)320 C maximum nozzle temperature[1]350 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[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)LeviQ 3.0 auto-levelling with Z-offset, plus area levelling[1]121-point auto-levelling plus partial bed levelling[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, filament entanglement detection and power-loss resume[1]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 pathMulticolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1]CANVAS four-colour printing with RFID filament identification and automatic refill - the defining difference from the bare Centauri 2[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documented"Powerful Self-Developed Motherboard"[2]
Total rated power drawNot documented1100 W at 220 V, 350 W at 110 V rated[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS, with pressure advance and flow calibration supported[1]ELEGOO OS; ElegooSlicer recommended[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen[1]5-inch colour capacitive touch screen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus slicing software, the Anycubic app and USB (print only); AI spaghetti detection and object-skip supported[1]Colour touch UI; STL, OBJ, 3MF and STEP input[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app, USB (print only)[1]USB and Wi-Fi[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][4][5]Not documented
Materials Support
Officially supported filament listPLA, PETG, TPU, ABS, ASA[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]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[6]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[7]

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.
