Right, and you have the choice, by individual axis, to have it
open-loop or closed-loop. The advantages with closed-loop are
that you can shut off the stepper drives and move the machine
manually without losing your axis coordinates, and that any
excessive following error can be detected. You can always add
this capability later.
