Dec 12, 2019 I would use a ball screw on the cross slide. Just snug up the gibs to keep it from back driving. I don't have any problem on my mill when using it in manual mode. Be sure to get a left hand thread ball screw else the cross slide will work backwards in manual mode. A 5/8 -10 ball screw would be perfect, that way your dial is still accurate.
