I have searched on here and the net but haven't found anything I understand to calibrate the axis. The axis move OK but don't move the right distance. How do I fix that? I have stepper motors. Also the Z axis works fine in the conf wizard, but once in the program it wont jog at all, it just moves a very small amount and stops.
Why might that be?? It did work but I was trying to get the calibrations right and went through it a couple times. BUT the setting that worked are the same ones it has now. Don't know.
The steps should be right as I have a 1.8 deg stepper with 16 micro-stepping and a 13 TPI rod that works out to 41600 steps per rev.
Thanks.

Hi
Try setting to 4x microstepping and revise your scale accordingly. (divide by 4)
41,600 steps is per unit (inch) not per rev, but still probably way to high and it is probably losing steps galore.
Also need to look at velocity and acceleration, in conjunction with max latency on base thread, but if reducing micro stepping produces an improvement
that is where the problem lies (step loss)
