For the powder bins I used a motor on each, 1mm lead threaded rod for
the lift.

I used two in case I need to lift the supply a little more than the
build lowers to account for losses. Perhaps I will find they can be
coupled directly or that one can have a 1/4" lead while the other has
a 1mm lead to give an automatic differential, time will tell.
