The front and rear board transport belts are driven independently by two variable speed motors. In-
evitably one motor drives faster than the other motor. It is necessary to calibrate these motors so
that they drive at the same speed.
Feeder motor speed is measured using a tachometer on the input or output pulley and adjusted by
a potentiometer control on each motor.
