@dc42 thanks for your reply
I can confirm the x and y do move after I over wrote the home all m564 s0 h0 but the z axis dont move And makes shuddering noise
If it's a Cartesian or CoreXY printer with a leadscrew-driven Z axis, that may simply mean that you have set the Z maximum acceleration to high in your M201 command, or the maximum speed too high in M201.
A bad crimp connection in one of the cables is another possibility. A faulty Z driver chip on the Duet is also a possibility. You may wish to test the two motor/cable assemblies individually using one of the other motor outputs connectors on the Duet.
