This happens each time the e stop is used, I know it does this so I use the esc key to just stop the machine, but in z down that will let the head freewheel.
I will call Tormach today and see what they have to say about it, may just need to tighten the gibs a bit more.
If its not a common problem, then I would think it would be mechanical as the dro reads the same before and after the gouge.
