Roxy, I have a few things after the LCD which I would like to change and hope you can help me.
The issue that suddenly developed is still there, the z stop triggers the x & y. We got a work around with lifting z, and that is okay.
Now I would like to turn the servo line in conf h off, to avoid the pauses. But I would like to make z move up 2-3 mm after homing z to untrigger the z stop and therefore make it impossible to trigger x & y. ???

How is the M851 different to the z offset in eeprom. It will be lost after a restart or turn off of the machine.
Also, can slicer pre codes be implemented in the fw?
