Startup Question

Simple question that I cannot seem to locate the answer:
No matter what offset I was using when I shutdown LinuxCNC I want my DROs to read 0 after I restart and then home. I can do this with the Touch-Off button in Axis but how do I set my INI/HAL file to clear offsets when LinuxCNC restarts?

Of is there a mdi input that would have the same outcome?

Thanks,
HH

yourmachine.ini  file,  in  [TRAJ]  section  POSITION_FILE = posfile.txt   stores machine positions at shutdown. If this is not set, the machine starts with all axes set to zero

 

Great! Thank you
