Hi there I am looking for a manual process for a bar pull program using mazatrol to compare too. I have done them before but it has been a while. I am on a mazak qtn 350 nexus lathe with a matrix control. The M code for open the chuck is 206 when it gets to that M code the program stops and I get an illegal M code alarm. I think I am missing something simple, I also have an M 5 (spindle stop) before trying to open the chuck but still not working any help would be great thanks
