Say, Hood, I tried to enable only your 2FROfeedhold.brn and I get an error in Mach3 that I can only get out of by incessantly clicking OK, or using Task Manager to kill Mach. Next time Mach3 starts it has that brain disabled. What is it I don't understand about this seemingly simple brain, or do I also need the 2SROFRO100.brn enabled for some reason?
