Important:
We recommend making the following changes only if you specifically require the full 270 × 270 × 256 mm³ build volume. Otherwise, we recommend keeping the printer in its default configuration.
¶ Why Is the Build Volume Smaller Than the Advertised 270 × 270 × 256 mm³?
This dimension represents the maximum mechanical travel of the toolhead along the X, Y, and Z axes. In QIDI Studio, certain movement areas are intentionally restricted to support features such as filament cutting and Z-hop.
Z-hop during retraction helps prevent nozzle drag and collisions with printed parts. When retraction is enabled, a small vertical buffer is reserved to prevent the heated bed from colliding with possible filament debris at the bottom of the chamber.
Additionally, the Q2 includes a filament cutter used with the QIDI BOX. A foldable stopper located at the front-left corner of the printer is required for cutter operation. When the toolhead moves into this area, the cutter lever presses against the stopper to cut filament.
To prevent interference during printing, QIDI Studio visually excludes this region. The unavailable area measures approximately 11 × 16 mm² in the front-left corner.
¶ How to Print Using the Full Build Volume
Before proceeding, understand the following limitations:
- The full build volume is available only when the QIDI BOX is not used.
- The filament cutter will be disabled when using this modification.
- The bottom of the heated chamber must be clean and free of debris.
- The total Z-hop height during retraction must not exceed 256 mm.
- Perform this modification only if the full volume is required.
¶ Remove the Filament Cutter and Clean the Chamber
Remove the filament cutter by unscrewing the two screws shown below.
After removal, clean any debris from the bottom of the chamber to prevent collisions when the heated bed moves to its lowest position.
¶ QIDI Studio Settings for Full Build Volume
In addition to the hardware change, update the following settings in QIDI Studio:
-
Update QIDI Studio to the latest version.
-
In Printer Settings, clear the Excluded bed area to disable cutter protection.
-
In Printer Settings → Extruder → Retraction, ensure:
Z hop while retraction + Z hop upper boundary ≤ 256 mm
This prevents the toolhead from exceeding the maximum Z height.
-
In Filament Settings → Setting Overrides, if retraction parameters are customized, also ensure:
Z hop while retraction + Z hop upper boundary ≤ 256 mm
