i tried it now and i think it works (did not have an error message and started like normal. But i got an error message when i had no xscrew.comp file)
if someone is doing the same: basically i created a new file called xscrew.comp, then wrote my machining area (every milimeter a new line): ... -2 -2 -2 -1 -1 -1 0 0 0 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5 ... (of course the second and third row of numbers need to be measured but i have no machine ATM, so thats why they are the same) and added once "COMP_FILE_TYPE = 0" in the HAL section of my INI file and for every axis i added "COMP_FILE = <AXIS>.comp" in the AXIS section of my INI file Am Samstag, 22.
