Anycubic Kobra S1 vs QIDI Q1 Pro — documented properties and sources
Property	Anycubic Kobra S1COREXY	QIDI Q1 ProCOREXY
Identity
Brand	Anycubic	QIDI
Class	COREXY	COREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)	Anycubic Kobra S1[1]	QIDI Q1 Pro, listed by QIDI as "Q1 Pro 3D Printer". QIDI traded as Qidi Tech until end-2024[2]
Release date (announcement and actual shipping)	Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3]	Not stated on QIDI's own product page; the page now carries a discontinuation notice instead of a launch date (checked Aug 2026)[2][4]
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]	$499.00 on both qidi3d.com and us.qidi3d.com, checked Aug 2026 — but the listing is marked Sold Out and the page states "This model has been discontinued". qidi3d.com shows it against a $599.00 regular price; the US store shows compare-at $499.00[2][4]
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][5]	Succeeded by the QIDI Q2, which QIDI's own comparison on the Q1 Pro page distinguishes as 270x270x256 mm (vs 245x245x240), 370 °C hotend (vs 350 °C) and 65 °C chamber (vs 60 °C). Do not read Q2 figures onto the Q1 Pro[2][4]
Market position: superseded? successor announced?	Not documented	Discontinued and out of production; QIDI states spare parts and support for existing owners remain available. Replaced by the Q2[2][4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable	250 x 250 x 250 mm[1]	245 x 245 x 240 mm advertised (QIDI). No independently measured usable envelope found[2][6]
Machine footprint (mm) & clearance needed (cable/spool overhang)	400 x 410 x 490 mm[1]	477 x 467 x 489 mm machine dimensions (QIDI)[2][6]
Net weight (kg)	9.37 kg net, 20.2 kg packaged[1]	17 kg net, 20.3 kg gross (QIDI). 3DJake lists the 20.3 kg figure as gross weight[2][6]
Frame construction & material	Not documented	Metal CoreXY motion frame with panelled enclosure; QIDI publishes no frame-material breakdown for this model[2]
Enclosure: open / enclosed; panel material; door/lid	Fully 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][5]	Fully enclosed with independent chamber heating to 60 °C; QIDI does not publish the panel materials for this model[2][6]
Passive chamber temperature reached (if enclosed; measured values preferred)	Not documented	60 °C, actively heated (manufacturer claim — this is a heater setpoint, not a measured passive figure)[2][6]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)	CoreXY (stated outright in Anycubic's specification table)[1]	CoreXY[6]
X-axis guide type (rods / linear rails / V-wheels; size)	Not documented	10 mm linear steel rods with automatically tensioned belt (manufacturer description)[6]
Z-axis: leadscrew count & type, sync mechanism, anti-backlash	Not documented	Independent dual Z lead-screw motors[6]
Speed & Acceleration
Max print speed (claimed, mm/s)	600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]	600 mm/s, worded by QIDI as maximum tool-head speed (manufacturer claim, not a sustained printing speed)[2][6]
Recommended/typical print speed	300 mm/s recommended print speed (manufacturer figure)[1]	Not documented
Max acceleration (claimed, mm/s²)	20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1]	<=20,000 mm/s2 (manufacturer claim)[2][6]
Extruder
Type (direct drive / bowden) & design name	Direct drive ("short distance extrusion")[1]	Direct-drive extruder with hardened steel gears[2][6]
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]	Tri-metal hotend with a ceramic heater plate and a bimetal nozzle, 0.4 mm standard[2][6]
Max nozzle temp claimed AND firmware max temp limit (both values)	320 C maximum nozzle temperature[1]	<=350 °C claimed. No firmware max_temp verified for this model[2][6]
Heated Bed & Surface
Max bed temp claimed AND firmware limit	120 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]	<=120 °C claimed. No firmware limit verified for this model[2][6]
Bed surface (material, texture, coating), single/double-sided	Not documented	Double-sided textured PEI plate on an aluminium substrate bed[2][6]
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]	Automatic levelling; QIDI markets it as "hands-free automatic levelling" with dual sensors, without naming the probe technology[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 fitted; QIDI also lists filament tangle detection without describing the mechanism[6]
Multi-material/multi-color capability or official upgrade path	Multicolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1]	Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting design	Not documented	Auxiliary part-cooling fan plus a chamber circulation fan (fan count and duct design not published)[6]
Electronics & Power
Input voltage (110/220 V, switch or auto)	Not documented	100-240 VAC, 50/60 Hz[6]
Total rated power draw	Not documented	350 W plus 300 W for chamber heating (rated)[2][6]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)	Kobra OS, with pressure advance and flow calibration supported[1]	Klipper, running on a 64-bit processor per QIDI. Exact fork and version not published on the product page[2]
Connectivity, UI & Camera
Display: size, type, touch?	4.3-inch capacitive touchscreen[1]	4.3-inch touchscreen, 272 x 480[2][6]
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]	Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-drive	Printer UI, slicing software, Anycubic app, USB (print only)[1]	Wi-Fi 6 (QIDI states "150M 2.4G") and USB 2.0. No Ethernet listed for this model[2][6]
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][5][7]	Built-in camera, up to 1080p, timelapse supported. Framerate not published[2][6]
Calibration Routines & QoL
Assembly level & time from unbox to first print	Not documented	Ships fully assembled[2]
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)	Not documented	Power-loss recovery listed as a feature; mechanism not published[6]
Materials Support
Officially supported filament list	PLA, PETG, TPU, ABS, ASA[1]	QIDI lists compatibility with common filaments; storage 32 GB eMMC. No per-material list published on the current page beyond the general claim[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[8]	1-year coverage, 14-day no-reason return, lifetime tech guidance (QIDI's standard terms as shown on its store)[9]

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.
