It all works as intended, but of course with raising the z we overcome the issue I had, by just lifting z. This is something I did not have to do, but I guess I can live with it.
It's a shame that we cannot prevent the z stop to trigger x&y too after g29.

It saves the matrix to eeprom.....that is fantastic!! For some reason my offset nozzle/sensor is not right anymore??? But I can adjust that easily.
