- Nov 25, 2013Luis,
As you have the same recurring problem with different versions and I
don't remember seeing this being a problem nor have I experienced
this, I would suggest possibly a mechanical problem.
Have your checked to make sure your couplers between the steppers and
the shafts are tight and not moving?? I have had that happen in the
past when I thought for sure I had properly tightened them on!
