Are there any major pitfalls in my thinking?
2 hiwin slides on each gantry post 90deg opposed and ball screw driven.
Any thoughts?

I am sure that I have seen some pics on here of what you are looking for. If I am not mistaken Dean (Jazzcnc) put them up. The Y gantry acted like a Z with twin screws. ..Clive
