I had decided to go with slaved motors but I really want to use a CSMIO/IP-M Motion Controller and they don't like slaved motors. Early on I had toyed with a belt drive and after reading posts on biketrialdave's build log I'm heading back that way I think. The belt will need to be made as it is over the size limit for standard belts but the cost of a custom one does not seem extortionate! The basic idea is as the image above... which would not require much modification from the existing setup. As usual, any comments are gratefully received!
Hi Joe,
I wonder if that long unsupported run of belt would flap and vibrate around. Do you think it would be in perfect syncrony on each ballscrew? Also, a single motor would need to be more powerful than 2 singles.

On my new machine (not CSMIO) I am going with 2 motors and 2 short belts, then one long slave belt between them which mostly does nothing unless there is a problem. Would CSMIO let you feed step/dir signals into 2 drives? Is that acceptable? I know you can't 'slave' home in the traditional sense with that suggestion, but with a link belt you wouldn't have to.
