Every couple of hours of operation one of the axes's move .0004. I mean exactly .0004.
So I make a .0004 move and they come out deadly for a couple of hours, then bam...0004 out.
The Z axis and the X axis don't move even a tenth in 10 hours of full rpm operation and 100% rapid. I'm figuring the 4 tenths is a metric thing.
Anybody ever run into something like this before?
