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.
