Thanks Peter, going for a look at those belts.

On the Driven Nut plan, found a company that make through shaft servo motors.. specs look promising.. but, they look really, really expensive.. Iv requested a quote so I’ll post back when they get back to me.

Going back to the Angle Iron talk, I’m now thinking about H beam, 100x125 or 100x150. I’m thinking about making the machine basically sit on the floor, and then make my work table suspend from the roof and lower down over the CNC when it’s not in use.

I'd definitely love to hear the pricing when they get back. The axial length of this kind of a solution is an issue in smaller machines, but smaller machines also benefit less from the inertial reduction of a driven nut application.
