ABSTRACT:
A circuit inserted between a microprocessor controller and a stepper motor driver uses a detector to detect single peak or double peak pulses from the controller and selectively produce one or two motor steps for each controller program loop, and a time delay circuit to regulate the time of the second step to yield a substantially regular stepping rate.
