If you have tried calibrating the Mini and adjusting the Z-axis offset, but you are still having issues. For example, prints won’t stick to the print bed, or the tape on the printing bed has been scratched, we recommend following this guide to adjust your X-axis support.
Connect to a PC, open XYZware, and click on Printer monitor > Setup > Jog mode. Then click Home axes.
Check and make sure the Extruder module has returned to its home position.
Move Z-axis up by 10mm.
Manually move the extruder module to the right.
Open the black cover on the left-hand side of the machine.
Take the leveling tool supplied with the da Vinci Mini, and place it on the print bed under the X-axis support.
Unloosen the 4 screws manually, but do not take them off completely.
In Jog mode, move Z-axis downward by 1mm.
Repeat the above steps until the X-axis support and the leveling tool are flush.
