hey guys, got some mad backlash going on in the Z axis on my ST30ATC m/c - i'm talking nearly 1mm of lost motion.
Here's a video of me hand wheeling 1mm... (after going 1mm+ setting indicator then 1mm-)

Clearly not ideal! where should I start looking? could this be as simple as a thrust washer issue (ball screw turning but not transferring the force)
I'm also able to rotate the ball screw a very small amount by hand, is this also no bueno?
