The Z axis of the cyclone has a couple of thou backlash until very recently. Not I can push and pull the tool turret 0.4-0.5mm, I am pulling from the base as close to the ballscrew as I can get so guessing that it is either worn ballscrew or the bearings. Seems to have coincided with me taking off the chuck and removing software limit and doing a job on a faceplate.
Does anyone have any idea on how to pinpoint where this play is and eliminating it?

Can you check to see if the movement is withing the nut or ballscrew mounting? When you pull it back and forward is the screw moving with the backlash or is the screw staying in the same position but the saddle moving? If the screw is moving then check the mounting bearings at the end of the screw.
