rubbing on end stop or the track.

Set the motion sensor to “person” and move the cart with your hand while motion

sensor is active. Set motion sensor to capture “position.” Make sure you see a

smooth position plot on the display. If there are any large jumps on the plot rotate

motion sensor around the Y axis until you see a smooth plot with no jumps

throughout full range of cart motion. The sensor is now aligned.
