Ball screws are required with a CNC mill. While CNC control is on the servo or stepper holds the screws tight all the time. In manual though the ball screws will move (creep) when not intended. The original acme screw has more hold on the non moving axis. So if you have ball screws you need to always tighten down the non moving axis.
