However, that experience has shown that building the gantry STIFFly

YES!!

Build the framework / gantry so that it is stiff and secure. Then use only
one lead screw and one drive motor. This is how most of the professional OEM
guys do it. I have worked on and installed CNC routers with tables 4 meters
long (X) and 2 to 2.5 meters wide (Y) that used only one screw with the proper
drive motor. Of course the screws were nice and "beefy" and these were servo
drives, not steppers. Using 2 screws with steppers could be a nightmare to
sync.

Hope this helps some.
