Downloaded it last night - thanks! I think I'll stick with
store-bought steppers so I can have the 400 step/revolution
resolution.

Probably just as well. The resulting stepper not only has a lot fewer
steps per revolution, but not a lot of torque. They are just not made
for that duty, and while they will work, are not anywhere near as good
as real steppers.

If you happen to know, what is the holding torque on your ShopBot
steppers?
