Geeetech MizarM

The Geeetech MizarM is an FDM 3D printer from Geeetech with a 255 x 255 x 260 mm build volume.

Calibration

• Start by treating the Mizar M as two printers in one, not one single workflow.

Action: Before any slicing or first print, decide whether you are calibrating for the Separated Color Module or the Gradient Color Module, because each mode has a different mechanical and flow behavior. Use the same baseline machine checks for both: verify belt tension on X/Y, confirm the dual Z axes are synchronized, and inspect that the hotend module is seated firmly in the carriage.

Common defects

• Pause/resume reliability is reported as weak in at least one hands-on review.

Symptoms: A paused print may not resume cleanly, or the restart behavior may be inconsistent enough to make the feature unsuitable for unattended production.

Likely cause: Firmware or motion-sequence fragility during state restoration, possibly amplified by the additional complexity of the dual-module system.
