Hello,

I have a DLP printer , similar to B9 models and I am having trouble with the Z Axis, the pieces are sticking to tray.
The Z axis ismoving up/down correctly and the z movement speed is correct, too. I did the calibration few times but it seems to be not the problem, as the results are always coming out the same.
This issue could indicate a bad stepper motor?

This is the print results x project

Does anyone know how to solve this?
