The easiest method is mechanically connect the two sides with a shaft along
the gantry and use one motor. Then it *cannot rack* or have any of the other
issues that can happen with driving both sides of a constrained axis with two
motors.
If you need more Z height, you can elevate the racks on the sides. Or run
chains or belts from the cross shaft ends down to stub shafts with the pinion
gears.

About how to drive both Y joints as one axis: I've read that there's a way
of simply adding two Y joints for the Y axis in the 2.8 master branch but I
don't know if there's documentation available already.
