Ad,
Is there a way to run only the z axis for exactly one revolution? My original measurements of the thread pitch for the screw are wrong so I would like to run the drive for one turn and measure the distance travelled with my dti.

Regards

Just tell it to move a distance equal to the pitch of the thread, then it will do one turn and you can measure.

Alternatively use any distance, measure the actual distance and that gets you a ratio. You can then scale the pitch value you entered from that - hopefully it'll be a recognisable number.
