Hey fellas,
I was wondering if one type of bridgeport (or other brand names) or year was better for converting to cnc over another. I have heard that a bridgeport boss that has been put out of use b/c of out of date control systems are good and cheap. I just can't understand the difference between the boss and a manual mill. How much slack can a mill have in it and still be accurate for a cnc conversion? The largest stepper motors I can find are 1200 oz and I was thinking about using gear reduction 3:1. Will this provide for a fast mill with lots of power or just kind of a getrdone thing. I not expecting a machining center but would like for things to run pretty smooth. Thanks for your help. Oh yeagh do you power the z axis from the quill or from the knee feed?
Thanks
Chris
