Hi there

I've got a really strange problem. 

While I was trying to solve the problem about losing X reference while tool change I figured out what the problem was or is.

As soon I start the spindle motor (servo motor), the X position changes about -2 mm, but only in Mach4 at the DRO not on the machine. And it changes the position in the work coordinates and also in the machine coordinates but at the machine itself, nothing happens no movement. So during a tool change the motor stops and no its clear why the X position is not the same after tool change but I’ve no idea what this could be.

I’ve made a video to show the problem.

Could anyone help me with this problem?

Cheers
