So it turns out using an end switch actuated by a spring loaded screw is not the most precise method of setting your extruder in the home position, upon watching people mount hall effect sensors actuated by magnets, or ultrasound proximity sensors for both bed leveling or as endstop (even saw a guy using a laser measurement system in his extruder) I clearly saw how overcomplicated we make our stuff.
So lets keep it simple, for me, you, and every one who does not have to time to draw and etch a circuit and write a code for a sistem where only a 5v signal will do the job perfectly.
On the picture above there is a Infrared sensor, its datasheet as a PDF file show us the simplicity of its working, you load it with 5-24V on the (+) Brown and (-) Blue wire, and as a Result sticking something between the infrared will give a signal out of the white wire the same voltage of the input, easy as that.
Moreover, the precision of it is around 0.03mm (in your face Hall effect sensors!) and tha
