EMC was designed from the ground up for servo systems, and it is only a
later mod to support steppers, both open-loop and with encoder feedback.

No subroutines right now. This is kind of a sore spot. It DOES have variables,
and I have done some stuff using variables that would have been done as a
subroutine otherwise. This required me to sit there hitting the start button for
each cycle through.

Well, you can get one or the other. I don't know of any system that allows you
to get both step/dir and analog voltages at the same time.
