The OP should bear in mind too, that if he is also powering down the motor drivers of a stepper driven system, there is a small 'leak' in this because the stepper drivers, if multistepping, don't remember where in that sequence they were, so the motors are jerked to the nearest full step at power up. Its small, and probably random but it is there. Depending on the gearing it could be a thou either way.
