Yes Jim is right, I never picked thgat up. When I read it I thought you were measuring the first travel and it was correct then you were coming back again to measure the backlash. Measurement needs to be taken in one direction and also even though you have good ground ballscrews with little backlash there may be backlash in other areas such as the bearings or brackets. However your return to zero test has shown Backlash is not your problem but you need to confirm the initial movement as Jim suggested.
