Do you have any idea or an example of how much runout that can be accepted in a ballscrew?
Offcourse its hard to answer and its related to length but i was thinking that maybe you have a general idea?
Im asking because i had some of mine modified in the ends for different reasons. The guy who did it is an experienced machinist used to high precison machines so i guess that in his world my screws are pretty bent. I dont remember exactly but i think that my 900 mm screw where off by 0,4 mm. Im gonna check for myself when i get it back but i think the measure he referred to was when the screw was laying flat and you measure from the flat surface up to nearest point of the screw...

Cheers
