Description
This is a much more accurate Z endstop!
You'll notice how accurate/stable it is immediately!
Watch it in action:

See the video at the time: 3:57 to see the first version I made:

It's very simple just two screws, the lower screw is with flattened end, the upper screw is with sharp end (wood screw). You need to change the endstop logic in the firmware to NC (if it's not NC already).
You will be using two pins only Signal (S) and Negative (-).
DON'T USE THE Positive (+) pin, we don't need the 5 volts.
Before wiring it, adjust the upper screw so it's BARELY touching the lower screw (for the best sensitivity), you can use a multimeter to make sure if it's working as it should.
*The Slower you home Z the more accurate it is (this applies for any Z sensor).
