The problem is that the dimensions of the model are not the true ones, and i can not figure out how to configure the machine to work properly.
For what concern the XY axis, i can configure the axis simply correcting the scale through the machine settings of CW, but for the Z axis i'm having a lot of problem.
i'm using a stepper motor (1.8deg/step, 200 step/turn, 1/16th step drive) connected to a trapezoidal screw with a thread 10x3 DX.
The arduino code is this: .
which is the true procedure to configure the machine Z axis? thank you in advance.
