Hey Charlie thanks for the interest.
I would live ballscrews but can't be chewed to sit and design the rotating nut for the screws. I already have the rack and pinion drives so it's not a problem just a case of getting some longer mod1 rack.
The toughest thing I plan to cut is ali. But the machine will mainly be for wood and acrylic.

I thought you had used those drives on another build? The rack and pinnion does seam nice on my build I have done but I was thinking that screws would be the way to go posable. if you have the drives already though then your half way there.
