The Z-axis focus calibration of the laser module is performed by detecting lines engraved on cardstock to determine the deviation between the laser and the hotend nozzle in the Z-axis direction, thereby completing the focus.
Causes of focus failure include:
The test material used does not meet the requirements.
The test material is uneven or warped.
The laser engraving area already has marks, making the engraved lines difficult to identify.
Users may adjust the order of these solutions as needed.
Refer to Laser Focus Calibration Introduction to check whether the material settings for focus calibration are appropriate.
Use the recommended 350g cardstock or other suitable alternative materials.
Ensure the material is placed flat on the laser platform blade strip, without warping or deformation.
Place the cardstock near the homing platform on the laser platform.
Use clean cardstock (ensure the engraving area and its surroundings are free of marks).
After completing the above checks and adjustments, retry the corresponding calibration procedure.
