Not wanting to put you off but don't go the TB6560 route if at all possible. Forget Printer/scanner steppers for anything other than 3d printer they just haven't got enough guts.

You'll be much better waiting and watching for some cheap M542 type drives to come up and running them of a cheap 36V supply with nema 23 motors. This will give you ok speed and some reliablity.

But well before this lot is needed you'll be better advised to put time into the machine frame and what your going to build it with.!
Unfortunatly it's double edge sword when it comes to building on the cheap.! . . . Doing it cheap often means using higher friction linear components, like threaded rod, skate bearings etc which conflicts with lower spec/power electronics has they are stickier so require more Umph which you haven't got.

Think about the design first and then build the frame before buying any electronics.!
