sorry, i don't want to try this a third time, because it diggs very hardly, and the forces are high (dont want to destroy my nozzle)
When i analyse the code i can see following:
in lines above it is at position Z3.3
then the pause script starts and moves the head down to 1mm ---->>> G1 F300 Z1
then the scriptz elevates it to 15mm --->>> G1 F300 Z15
thereafter back to 3,5 G0 X144.47 Y126.99 Z3.5 (what would be alright.
The code to move the head down to position 1mm is definitely wrong --- buggy script
