QIDI Q2 Setup Guide: From Unboxing to Your First Print

The QIDI Q2 is an enclosed CoreXY printer with a 270×270×256 mm build volume, a 370 °C nozzle, a 120 °C bed, and active chamber heating up to 65 °C. It ships almost fully assembled, so going from box to first print takes about an hour — only fifteen minutes of which is hands-on work. This guide walks you through the whole thing: what's in the box, assembly, removing the transport locks, first boot, auto-calibration, networking, loading filament, and dialing in the first layer.

What you'll need: a sturdy table with about 0.5 m² of space (the printer weighs 18.1 kg and measures 402×438×494 mm), a 220–240 V outlet, a spool of PLA for the first print, and a computer or phone if you want to slice and send over the network. Every tool you need for assembly is already in the box.

Step 1. Unboxing

The box is heavy (18 kg), so lift the printer out with a second person or set the package on the floor first. It's marked "Glass Fragile" for a reason — the door and top cover are glass. Remove the foam lid, lift the printer by its frame (not by the gantry or the print head), and gently peel off the film. Check the contents against the list above right away — small extras like the spare-parts kit are easy to lose in the foam.

Step 2. Assembly: screen, spool holder, power

Assembly takes about ten minutes and needs no tools. First plug the touchscreen ribbon into its connector, then seat the screen in the groove on top and slide it right until it clicks. The spool holder bolts onto the rear panel, which also carries the Ethernet and USB ports. Connect the PTFE feed tube and the power cord — the label by the inlet lists the 220–240 V working range. Don't power on yet; remove the transport locks first.

Step 3. Remove the transport locks

From here the printer prompts you on-screen, but here's the gist. Undo the four screws holding the bed down — without that, the bed can't move on Z. Following the wizard, wait for the bed to rise and pull the foam out from under the platform. Then cut every transport zip tie, including the one securing the print head. The community has one specific warning: don't miss the zip tie on top of the Z lead screws — it's easy to overlook, and the printer won't calibrate with it on.

Step 4. First boot and language

Flip the power switch at the back. The setup wizard launches and starts with language selection, then walks you through the same unpacking steps with pictures (in case you missed anything) and runs a self-check of the heaters and fans. The printer is ready to go about a minute after power-on.

Step 5. Networking and firmware update

Set up the network on the screen: Settings → Network, turn on Wi-Fi, pick your access point, and enter the password. Prefer a cable? Switch to Ethernet mode and the IP is assigned automatically. To print from a slicer over the network, find the printer's IP under Settings → General Settings → Network, open the Device tab in QIDI Studio, click "+", and enter that IP. There's Klipper underneath, so you can also drive the printer from the Fluidd web interface — just open the printer's IP in a browser on the same network.

QIDI recommends running an online firmware update as soon as you receive the printer. Don't roll firmware back to an older version. After updating, re-run auto bed leveling and Input Shaping — skip that and print quality suffers. If you have the QIDI Box version, power the Box off before updating and only turn it back on once the update finishes.

Step 6. Auto-calibration: bed leveling and Input Shaping

Calibration runs on its own. The Q2 has no separate leveling probe — the nozzle itself is the probe: it taps the bed, and a load cell in the print head reads the force. That gives a consistent first layer with a near-zero offset, and it also means you can print not only on the stock PEI plate but on glass too — the sensor doesn't care what the surface is.

After leveling comes resonance compensation (Input Shaping): the head jerks rapidly along each axis to measure resonances. Don't be alarmed — owners report it can take up to 10–15 minutes, and the vibrations can be strong enough to shake the whole bed. That's normal and a one-time deal (a shorter version also runs automatically before every print). If you'd rather, you can disable the pre-print leveling in settings.

Step 7. Loading filament

Put the spool on the holder and feed the filament through the PTFE tube into the external feed port until it stops at the print head. From here you have two options. In automatic mode the printer heats the nozzle and feeds the filament itself — just confirm that a smooth stream comes out of the nozzle. In manual mode, set the nozzle temperature for your material (around 220 °C for PLA) and, once it's hot, tap the feed arrow. There's a runout sensor at the inlet, so the printer stops on its own if the filament runs out or snaps.

Your first print

You don't need a computer for the first print: the printer already has sample models in memory (the classic 3DBenchy among them). They're sliced for PLA, so load PLA — the bundled sample is only good for a part or two, so buy a spool ahead of time. On the screen, tap Local, pick a model, confirm the loaded filament, and start. Your own models can print from a USB drive or get sent from QIDI Studio over the network.

Dialing in the first layer and Z-offset

The load cell usually nails the first layer, but sometimes it needs a nudge. If you see gaps between the first-layer lines, the nozzle is too high — lower the Z-offset. The easiest way is to tune it live during the first layer: wait for it to start, tap the Z icon on the screen, and adjust in small 0.05 mm steps, pausing a second to see the effect. The value saves automatically. If the first layer just won't stick, check that the bed is clean — wipe the PEI with isopropyl alcohol and avoid touching the surface with bare hands. For a full breakdown of every cause, see our first-layer guide.

Fine-tuning: flow and pressure advance

QIDI Studio's stock profiles are good enough to start, but when you switch filament brands or nozzles it's worth calibrating flow and pressure advance. On the Q2, pressure advance isn't measured automatically — you find it with a test print. The slicer offers three modes: PA Line, PA Pattern, and PA Tower; print one and pick the cleanest result. Flow is just as easy to dial in. QIDI supports OrcaSlicer and PrusaSlicer alongside its own QIDI Studio (which is built on Bambu Studio), and many owners switch to OrcaSlicer specifically for calibration — we cover that step by step in our OrcaSlicer guide.

Engineering materials and multicolor printing

The Q2's strength is engineering and high-temp materials. With a 370 °C nozzle, a 120 °C bed, and an active 65 °C chamber, it confidently prints ABS, ASA, nylon, polycarbonate, and carbon-fiber composites — things most budget printers can't touch. The bundled hardened bimetal nozzle handles abrasive filaments. One caveat: large ABS parts sometimes pop off the PEI plate as they cool — for those, glass is the better surface (the sensor measures through the nozzle, so swapping plates doesn't bother it). If parts still warp, check our warping guide, and for ABS fumes see our ventilation guide.

Multicolor is optional on the Q2 — it's handled by the 4-spool QIDI Box, which also dries filament while it prints. But on early units reviewers (Tom's Hardware included) hit heavy friction in the feed path and constant jams: for reliable color swaps the Box is best approached with caution for now, though it works great as a dryer. If multicolor is a priority from day one, look at the QIDI Q2C instead, which integrates the CFS system out of the box.

Common first-run problems

• Auto-leveling throws a probe error. Usually a forgotten zip tie on the Z lead screws or unremoved bed screws. Clear every lock; if a Z screw binds, that's a factory misalignment you fix mechanically.
• First layer won't stick. Tune the Z-offset live during the print (Z icon, 0.05 mm steps) and wipe the PEI with isopropyl alcohol. Full rundown in our first-layer guide.
• PLA softens and grinds in the feeder. PLA heat-soaks in an enclosed chamber: slide the sunroof cover back and don't heat the chamber for PLA.
• Large ABS lifts off the bed. Print those parts on glass and fight warping — keep the chamber warm and drafts out.
• The slicer won't let you start a print. The filament on the printer screen and in QIDI Studio must match. If they don't, set the same material manually and sync — otherwise the software blocks the start.
• Filament jams while loading. The PTFE path to the extruder bends sharply; straighten the tube, and if that doesn't help the community prints a top-cover riser. For nozzle clogs, see our clog guide.
• The printer drops in and out of the network / the app shows offline. The software is a bit raw early on; wired Ethernet or LAN Only mode helps, as does re-adding the printer by IP.
• Stringing and wisps on prints. Dry the filament and tune retraction — details in our stringing guide and filament-drying guide.

What's next

The printer's set up — next, get comfortable with the slicer and routine upkeep. Read our full QIDI Q2 review for the model's strengths and weaknesses, learn OrcaSlicer for fine calibration, keep filament dry per our drying guide, and don't skip routine maintenance — lead-screw lubrication and cleaning. For abrasive and high-temp materials, keep a spare hardened nozzle on hand.
