QIDI Q2 Review: Enclosed CoreXY With a Heated Chamber for $485
In-depth QIDI Q2 review: an enclosed CoreXY with an active 65 °C heated chamber, a 370 °C nozzle and open Klipper. Print quality, noise, firmware, the QIDI Box and how it compares.
The short verdict: should you buy the QIDI Q2?
The QIDI Q2 is an enclosed FDM printer built on a CoreXY motion system, with a 270×270×256 mm build volume, a nozzle up to 370 °C, a 120 °C bed and an actively heated chamber up to 65 °C. At $485–539 it packs hardware you usually find in printers twice the price: a high-temp hotend, an enclosed heated chamber and open, Klipper-based firmware.
Short version: the Q2 is excellent at single-color printing in demanding materials — ABS, ASA, nylon, polycarbonate — and lays down a consistently flat first layer. Its weak spot is the QIDI Box multi-color add-on, which reviewers pretty much unanimously tell you to skip for now. If you want an enclosed, heated chamber for engineering plastics on a budget, it's one of the best picks out there. If multi-color is your priority, look elsewhere.

Unboxing and what's in the box
The printer arrives mostly assembled — two boxes if you got the Combo. The touchscreen ships detached and clips into place without tools. In the box you get an external spool holder, Ethernet and power cables, a toolkit, a flash drive and a paper quick-start guide. The Combo adds the feed hub, five PTFE tubes, cables, filament guides and desiccant for the QIDI Box.
The frame is steel wrapped in plastic panels: a glass door at the front, a sliding glass top cover, and plastic side windows. The interior panels are flame-retardant, and the printer is safety-certified by MET (US and Canada) and IECEE CB. The X axis runs on a linear rail, the Y axis on two linear rods, with motion driven by a custom 1.5GT belt. The Z axis is lifted by two independent lead screws with separate motors. The build plate is dual-sided textured PEI, and because the probe is built into the nozzle you can also print on glass — handy for large ABS parts.
Print quality
The Q2 is at its best with technical materials. The active 65 °C chamber and 370 °C nozzle deliver warp-free prints: ABS and ASA come out with excellent layer adhesion and a surface a passive chamber simply can't match. Russian outlet 3DToday specifically nailed PA12 nylon on the first try — at 310 °C nozzle, 110 °C bed and a 65 °C chamber. The dense-tooth 1.5GT belts noticeably cut vertical fine artifacts (VFA), so flat walls look cleaner than they would on standard GT2.
Not everything is perfect out of the box, though. On PETG several reviewers caught artifacts around bridges and overhangs: where the toolhead slows for an overhang and speeds back up, you get under-extrusion. The culprit isn't Pressure Advance (it's dialed in correctly from the factory) but overly optimistic stock speed profiles. On request, QIDI sent a tweaked, slowed-down file and the artifacts vanished. The upside of open firmware: QIDI Studio has a calibration tab that generates a tuning tower for you — you're not locked out like you are on printers with a broken auto-tune button.
The material range is impressive for a budget machine: PLA, PETG, TPU (95A and up), ABS, ASA, nylon (PA6 / PA11 / PA12), polycarbonate, PPS, PPSU, and even PEI and PEKK. For abrasive carbon-fiber composites and high-temp plastics, a wear-resistant tungsten carbide nozzle is the way to go.
Speed and noise
The headline 600 mm/s is travel speed; real print speed is around 300 mm/s at up to 20,000 mm/s² acceleration. For quality prints in technical materials you'll run even slower — roughly half the peak — and that's fine: the chamber and high temps are about consistency, not records. For reference, a test Benchy prints in about 18 minutes.
The Q2 isn't the quietest: around 50–60 dB while printing, mostly from the fans and the feed mechanism. A fan runs constantly even at idle, and the Input Shaper calibration at the start of a print sounds aggressive. It's fine for a workshop, but next to a desk it can get old — keep it in its own corner.
Software, firmware and updates
The Q2's headline technical feature is openness. Under the hood it runs Klipper (a QIDI fork) and access is wide open: you can manage it through the Fluidd web interface right in your browser, and slice in QIDI Studio (a reworked OrcaSlicer), OrcaSlicer or PrusaSlicer. Everything works locally over Wi-Fi, Ethernet or USB, with no mandatory cloud sign-up. That's rare in the budget class and a big plus if you don't want to depend on someone else's servers.
Firmware updates run online (recommended) or offline — unzip QD_Update.zip into a QD_Update folder on a USB stick and plug it in. Worth knowing: starting with version V01.01.02.01, control moved from the old QIDI Link app to the new QIDI Maker, and the old app is no longer supported on recent firmware. One more owner warning: official updates can occasionally desync the Z axis, so back up your settings before flashing. Minor rough edges include flaky networking and material-profile sync between printer and slicer that isn't always smooth (it's safer to edit filaments manually in QIDI Studio).
Multi-color printing: the QIDI Box and the Combo
The Combo bundles the 4-spool QIDI Box. And this is where the questions start. Tom's Hardware never got it to feed reliably: there's too much friction in the path — a too-tight feed hub and a 90-degree bend in the PTFE tube into the extruder. Even with a printed riser (suggested by QIDI itself), it would reliably feed one filament, not four. Color changes take 2–3 minutes and were unpredictable on early units. A second-generation Box added a lower access panel, new guides and an improved buffer, but the reputation so far is clear: as a filament dryer the QIDI Box gets praise (it can dry while printing), but as a multi-color system reviewers say skip it for now. If multi-color is essential, paying extra for the Combo is a hard sell.
Q2, Q2C and Combo — what's the difference
The lineup is easy to mix up. The QIDI Q2 has the actively heated chamber up to 65 °C. The QIDI Q2C shares the same frame and the same 370 °C nozzle and 120 °C bed, but has no active chamber heater (the chamber is simply enclosed, passive) and costs less — around $409. Combo isn't a separate model; it's the "printer + QIDI Box" bundle for multi-color. There's no "Q2 Pro" — if you've seen that search, it usually means the Q2 or the Combo. Simple rule: printing larger ABS, nylon or PC — get the Q2 with the heated chamber; mostly PLA and PETG and want to save — the Q2C is enough.
Pros
- Active chamber heating up to 65 °C, a 370 °C nozzle and a 120 °C bed — rare in the budget class
- Handles demanding materials: ABS, ASA, nylon, polycarbonate, PPS, PEI — without warping
- Consistent first layer: a load cell in the nozzle sets the Z offset before every print
- Clean walls: 1.5GT belts reduce vertical fine artifacts (VFA)
- Open Klipper firmware managed via Fluidd; slice from QIDI Studio, OrcaSlicer or PrusaSlicer
- Fully local operation with no forced cloud (Wi-Fi, Ethernet, USB)
- 3-stage air filtration (G3 + H12 HEPA + carbon) in a fully enclosed body
- Dual-sided PEI plate and glass compatibility; MET and IECEE CB safety certification
Cons
- The QIDI Box isn't ready for reliable multi-color — heavy friction in the feed path
- Weak stock profiles: overhang artifacts on PETG, needs speed tuning
- Flaky networking and material sync between slicer and printer that isn't always smooth
- A bit noisy (50–60 dB), with a fan running even at idle
- Modest 4.3-inch touchscreen (480×272) that also interferes with the door
- Not the best choice as a first printer — it expects you to understand calibration
- Firmware updates can occasionally desync the Z axis — keep a backup
How it compares
| Spec | QIDI Q2 | QIDI Q2C | Bambu Lab P1S | Creality K1C |
|---|---|---|---|---|
| Price | ~$485 | ~$409 | ~$399 | ~$559 |
| Build volume, mm | 270×270×256 | 270×270×256 | 256×256×256 | 220×220×250 |
| Chamber heating | active, 65 °C | passive | passive | passive |
| Max nozzle | 370 °C | 370 °C | 300 °C | 300 °C |
| Max bed | 120 °C | 120 °C | 100 °C | 100 °C |
| Print speed | 300 mm/s | 300 mm/s | 500 mm/s | 600 mm/s |
| Firmware | Klipper (open) | Klipper (open) | proprietary, closed | Klipper, closed |
| Multi-color | QIDI Box (opt.) | QIDI Box (opt.) | AMS (opt.) | CFS (opt.) |
Against its rivals the Q2 wins on temperature ceiling and openness, not speed. The Bambu Lab P1S prints faster (500 mm/s) and has a polished AMS ecosystem, but its chamber is passive and its nozzle tops out at 300 °C, so it struggles with nylon and polycarbonate. The Creality K1C is also fast and enclosed but lacks active chamber heating and costs more. An actively heated 65 °C chamber at this price is something almost nobody but QIDI offers.
Who the QIDI Q2 is for
The QIDI Q2 is a lot of capability for the money. The active chamber and 370 °C hotend are usually found in printers twice the price, and the open Klipper stack plus cloud-free autonomy will please anyone who likes to keep things under their own control. It's a strong choice for single-color functional parts in ABS, ASA, nylon and composites.
What it isn't is a no-fuss "first printer out of the box." The stock profiles need tuning, networking is fussy, and the QIDI Box isn't ready for reliable multi-color. If you're happy to spend an evening dialing it in and you specifically need a hot chamber, the Q2 is hard to beat on price. If you want the smoothest possible start and solid multi-color, look toward Bambu.
