steppers just quit moving mid motion but mach still running
« on: November 03, 2014, 10:42:04 PM »
havent changed any settings on this machine.  has ran relaiblly for a long time.  Today was running a job and all 3 axis just quit, and stopped where they were in the program.  In the mach screeen the program was still running.  Restarted everything and it ran fine for a little bit.  Did it again awhile later.  What would be the cause of this?  Any help would be appreciated.

Perhaps check your PSU output voltage when it all stops - the PSU may be going into thermal shutdown (or something similar).
