I am sure this was clarified on this list about two weeks ago. Servo
motors are NOT stepper motors with encoders. A servo motor has
somewhat more predictable and linear response, in general, than an
ordinary motor of the same general type. They are usually free of
cogging effects, where these may be pronounced in other motors.

EMC has much of this functionality built in already. Since it is very
modular, flexible and open-source, it is possible to add just about
anything you might want.
