General Mach Discussion / Why Not The Same

« on: July 10, 2016, 01:44:33 PM »

  Hi everyone. Newbie to cnc.  When I run the same program twice, the system takes different cnc patterns.  That would be ok except they didn't exactly match. In effect I ended up with two sets of parts when there was suppose to be one.  Sometimes the program would start in the left corner...when running the second time... the next pattern go to the right corner. Any suggestions?
