I found out on of the motor modules on the board was damaged. I replaced it with the extruder module and did a test... motor started moving both directions.

Hi. Have you found the cause of the problem? I have the same here... homing is ok, Z points are calibrated properly but it starts printing too high (about 5mm higher than the Z home position) and height between layers seems to be too distant so layers don't glue each other.

Hi. Did the new board work? I am facing exactly the same problem. Motors for Z axis only moves down. Everything else working fine...
