If you use an indicator, you should be able to isolate where the lost motion
is coming from. If you can see the screw turning before the slide is moving,
you are half way to the problem. Just find where the lost motion is at.
If the screw is turning and the slide is not moving, you have to determine
if the looseness is in the nut, in the screw mounting, or where the nut is
secured to the slide assembly.
How much "lost motion are we talking about and how much is there in the
other axis or axies. However you spell it or them (1 or 2)
