* Turn Left: Turning left requires opposite directional movement of the two stepper motors for a period of time. During this time, the steppers are first rotated in opposite directions an equal number of steps. For the remainder of the time, the stepper motors maintain position in the turning state. A short period before the time expires, they are returned to the initial state by rotating back the same number of steps. | * Turn Left: Turning left requires opposite directional movement of the two stepper motors for a period of time.
