new problem I have never seen. I set my steps right but EVERY time I jog the axis it moves .12-.25" farther along in x positive. it also does this in y axis in the negative direction and the z axis's both gain in zero.
its an older cmt machine with technic servos and drivers. I am using a break out board with mach 3 and an arduino to control the home switches/limit switches.
the "growth" is always in the same direction but not always the same amount.
I really need to run this machine. Im sure most guys here have been in this position.
