Please read very carefully from my second build log post #33 and from #133 to #140 .

That will answer all your questions. But before that, as was suggested above with a link to a calculator, find what's your screw maximum speed before it starts whipping for given length.

3210 screw is a very serious mass to move and to be snappy opposed to less than 1kg ball nut. Do your calculations, but the way i see it Rotating ball screw nut is the way to go and 400-750W servo motors each side.
