I have a file here where the Z refuses to go up.
It cuts a rectangle then a hole then another hole then z can't go up (just a buzz sound)
Always after it cuts the 2nd hole, Always!!!
See *** comment inside Gcode

Power problem? I unplugged X and Y servos same problem
Binding/ motor problem? Plugged X axis servo ( so I'm actually moving the x-axis) into Z port with other two servos unplugged same problem. the Z.125 code just buzzes servo.

Yet I can jog the mill all over with no problem
Its only this dam file that causes the problem.

I tried lower speeds etc. etc. etc.

I was able to minimize the code and still have the problem
One hole then G0 Z.125 and it fails.... see code below.

Can anyone try this code on deskcnc
