Oh, there have been attempts to do that. I know that Andy has something
like that and I myself also built a machine with fixed ballscrew and
rotating nut. The
That gets rid of the whip/critical speed problem but doesn't solve the
cost issue. In general, driving the nut is much more difficult than
driving the screw.
I have a Bridgeport Series 2 Boss and the X screw is driven via the end
of the screw off the left end.

The problem with the Bell Everman drive setup is that by the time you

A lot of that depends on your belt arrangement. They make linear
motion belting with a unique tooth profile. They use steel cords in
polyurethane belts to minimize stretch and they can obtain zero backlash
