Emco Mentor Mill conversion

[Ross77]

So now its time to sort out the ball screws. Or actually the fixing and motor drive arrangement.

I have decided on 5 mm pitch and hopefully a singly suported 2005 on the y axis and double supported 1605 on the x axis but I still cant decide whether to direct drive or use pulleys! probably a silly question but any serious for's and against's?

I have been looking over the build logs and remembered/found Robins old warco conversion, I really like his idea of retaining the manually control. but not sure if it is worth the extra work or if it would put undue strain on the end of the ballscrew.



The other way to do it is with a pendant or such like and manually control it electronically :0) again not sure which will be the most useful.

any advice or suggestions?
cheers
