OK I have gotten my screws and it seems i have about .001 on the y axis and about .0035 on the x is this normal for the cheap HIWIN rolled ballscrews or should i keep messing with it .Man i have shimmed tighten and everything a million times. this is a old bridgeport maybe a 1957 i just put the screws in about 2 months ago and i just cant seem to get it down to zero backlash any ideas OR IS THIS AS GOOD AS IT GETS. I only have the x-y " old centroid brackets" done im still making the z axis
based on chris brunos plans
