Tim;

Here is a link that may be relevant
from the quick scan I did it doesn't seem that they are using the encoders
to close the motor loop so much but to give overall position feedback
there are some good reference links for encoders,steppers,drivers,etc
including some good code examples for software PWM microstepping
worth a look
