Darn. I was hoping it would explain why my program goes wonky on almost every big job. Even with the display turned off. It just loses its place or misses a move and starts cutting in a totally new place. I'm frustrated as heck some days. I've upgrade the PC, controller motors, software, and brain damaged the computer OS and turned off all kinds of processes to the point that almost nothing runs except Mach 3. I constantly lube and adjust the machine to make sure its not binding. I just started trying setting Mach 3 as a high priority process to see if that helps. It just finished its first big job with out a major fubar. Well sorta. It was a 4 hour job, but I restarted it this morning aboutan hour and thirty minutes into the job from last night. I didn't have enough confidence to leave it running when I went to bed. I've got some 8-10 hour jobs I would sure like to be able to start and then go to work.
I'ld set it as real time, but I want to make sure I have a way to shut down the machine besides jerking the cord out of the wall. I think I'm just going to have to go with a servo machine with encoders next time around.
