The timing for stopping the slider is determined with the front and back through sensors.
The sensor to stop backward wiping motion is "Wiper position detection [A] (home position)", and the
sensor to stop forward wiping motion is "Wiper position detection [B] (backward)".
When moving backward from the home position ( in the picture below), the slider moves from the
back to the front side of the machine, with the wiper maintaining the upper position (retracted position).
The wiper descends around the backward slope at the end of this motion (starting point for the reverse
motion).
