Most Galil cards can be set up for steppers by jumper, if an encoder is used, it cannot be used in the same way as the servo PID loop, they run open loop still, and the position error is not generated.
AFAIK you have to keep interogating the encoder feedback in order to test for error and correct it by programming.
Also in stepper mode, the auxilliary encoder cannot be used.
