Do your threaded rods have a metric or imperial thread pitch?
The rods that nophead supplies in his kit have a 1mm pitch so the movement corresponds nicely to metric values specified in GCode. If you have something different and have not corrected for it in the Z steps/mm constant then you will get a cumulative error.
This, of course, assumes that your motors are not skipping steps or slipping at the Z-coupling but perhaps I should not assume that. Worth checking.

Try sending the axis up and down a few times and see when they get out of sync. If the motors don't have enough torque it will be on the upwards movement.
Note that if anything motors run cooler when they move compared to being stationary and energised.
