Hello everybody,
after small adjustments the Start- and Endcodes are running now a while, so here´s the final version 
It is tested with actual firmware, without noise reduction mode and only with Orca-Slicer (05.03.24: tested only with 0.4mm nozzle)
The Bed Mesh will only be done, if its tagged.
At end of print the toolhead will move to the cutter position and wait there. Don’t be surprised, that’s exactly what I want.
During this time the filament is moved back and the toolhead is waiting to be safe the filament is depressured and cooled down.
