5. Place a finger tip on the output shaft of the servo mo-
tor – the little white cylindrical protrusion – so that
you can feel when it moves.
6. The two movements that the servo makes (
C
) are a
pen-raising motion (counterclockwise, viewed from
the front) and a pen-lowering motion (clockwise, when
viewed from the front). Press Apply a couple more
times so that you can feel it move between the two
positions.
7. Stop toggling when you are certain that the servo is in
the pen-down position.
8. Pull the Z Slide up slightly, and press the servo horn into
position on the servo output shaft ( D ). It should point
straight down, or slightly towards the cable guide. It
must not point to the left at all, past the “Max pen-
down position” (
C
).
