Ball screw without bearings?
I saw a mill/drill retrofit package, a pretty nice looking one, and it looks as though the ballscrew is attached directly to the stepper shaft with no bearing in between, just an anti backlash coupling. The other end just floats in a simple bearing. Is this something anyone has any experiance with? It seems like Ive seen this done with some routers also. Any clues? Is this a bad/good idea?
