what do you mean with "motor out of sync?" and how could I solve it?

Hot bed and extruder are OK. I'm sure that the x axis doesn't remain levelled, because I measure it. it becomes not perpendicular to Z axis.

Hi William,

the problem occurs at the end of a print, when the motors turns off.
the left side of the x axis go down, slipping on the left screw. The antiback slash on the left screw does not work as intended and, when I start a second print, the right side of the X axis is far to high.

Hi all, I'm having severe problems with backslash. Everytime a print ends, the X axis slips on the Z right screw, the one where the extrusor is fixed, and the levelling became totally wrong.
I already tried to change the z nuts, but the problem is still there.
I'm wondering if it is possible to add ...

hi all,
this is my list of currently unsupported Gcode command on A30 firmware that I think are absolutely needed:

M290 (babystepping)
M221 (Extrude factor override percentage)
M303 (PID tuning).
geeetech, at now your printer lacks of the most crucial tuning features.
please, please, please ...
