Z Axis Change its position after breakpoint

rhobhrer

Hello.
I've notice a strange situation on Z Axis.
I press SHIFT + Pause to create a breakpoint to continue my work next day.
When I restart the work, I press Pause button to restart the process from last point.
But on my work I"ve noticed that Z Axis is about 0.5 mm down from it's original position and the work shows an irregularity on Z Level.

This not happens when I pause the process (pressing PAUSE) and restarting after sometime. In this case, I do not turn off my CNC and DDCS.

Somebody had this issue?

Regards.

Turn off machine
Put your hand on the Z axis
Try moive it down (be carefully!)
If the force to move is small, this can be problem.

In any case, restarting the job (after turn off machine) without fixing the coordinate system is a bad idea.
