Are these SEM motors? Those are AWESOME, but you can't get full output
from them with a gecko. Of course, they will break things if you ever DO
supply peak input to it.

Well, given this info, your numbers may be right. But, you should not
be thinking
of maximum rapid feed. You should be concentrating on what linear force
at the table
you need to create. I designed for 1000 Lbs of force on the table for
my Bridgeport
retrofit.
