Good point on the minimum speed, hadn't thought about that. Will track down the manual for the plasma cutter, it listed voltages and speeds to different materials and thicknesses. When cutting by hand speed seams to help but has to be consistent (which of coarse you'd achieve with the cnc drive), one small jerky motion and you loose the cut.
On one of the previous dreams of having one of these I'd thought of the timing belt method Steve. The belts are pretty strong but my concern was stretch when you changed direction. Kind of a bounce effect, maybe nothing to worry about though.
I like the added sections. That would be doable with a rack and pinion.

Free advice is worth exactly what you payed for it.
