The gantry (X axis) will have a ballscrew on each side driven by separate
motors. With ten foot ballscrews I have to use rotating nuts to avoid
critical frequencies.

The motors will be driven with G340's. These can be driven from one
step/dir signal or with the W-follows-X feature in CNCPro. Depends on the
degree of pitch variation between screws. The interface card (wonderboard
rev.8) will shut all amps off if one goes into fault.
