Why does my computer lock up after running a small program a number of times?
If you have a version of EMC earlier than 4.37 the problem may be due to a buildup of CPU usage caused by running the same program over and over. (CPU usage is shown in a small window near the bottom right of your screen.) Rebooting each time will work but is time consuming. Ray Henry suggests your best solution is to turn off the Backplot program when running short programs repeatedly. Another work-around is to copy and paste a number of copies of the small program into one longer program. Put a M0 command between each copy of the program to pause the machine. When you replace your part, just hit the [Resume] button to continue. This issue has been resolved in versions of EMC from 4.37 on.
