The system includes a rotation disengagement mechanism configured to disengage a rotatable shaft from a powered drive unit such that upon disengagement the powered drive unit is no longer able to rotate the shaft. After disengagement, the rotatable shaft may reengage the powered drive unit at only one rotational position relative to the rotation disengagement mechanism. A target coupled to the shaft is thus always in a known home position. The systems and methods further comprise smart positioning logic that assigns a number designation to four rotational orientations spaced 90° from one another.
