Hi Guys and Gals,
I'm in the thinking it through stage on a new mill, and I'm looking to design and build a small mill (about 300x300 cut area) which would be dedicated to cutting prototype printed circuit boards and panels. I already have a 6040cnc, which does a pretty good job on the boards, but I do run into some issues when dealing with small surface mount components and high densities of thin tracks. I've also had a few moments when I've had little time to work on my hobbies, and being able to run two mills at once (one cutting pcbs, one cutting other stuff) would be great.
Ideally I'd like to have the ability to make very small movements and to have a high positioning accuracy, and I'm perfectly happy to sacrifice speed in order to get it.
Has anybody got any suggestions for a suitable drive method (i.e ballscrew, trapezoidal lead screw, threaded rod, rack and pinion etc)?
Does anybody else do much work cutting pcbs and if so do they have any suggestions?

Options for high positioning accuracy?
