I have this strange behavior in my new Ramps rebuilded Orca.
(I fried the Gen6 and now try to rebuild the Orca with Ramps 1.4 on Arduino Mega)
X and Y are fine now. They move in right direction and home nicely in my new opto's
Z will only move some small steps down, not up and if I say Home, the z-motor will give a high tone for some time and than all is quit again. It does not move.
When I exchange Y and Z motors, this happens with the Y table, So I presume the Z stepper is fried, However,
When I exchange the Y and Z steppers, the problem is the same.
So it looks that it is not the Z-stepper.
Can I have a faulty Ramps or a faulty Arduino beneeth ?
