This was actually fairly easy to setup and only cost about $8 and 30 mins of my time.

First you need to order an Inductive Sensor:

https://www.amazon.com/gp/product/B008FZC8F2/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Then I printed out a new sensor mount and glued it right next to my hot end.

Then in the Marlin Firmware, I enabled the auto bed leveling code and flashed the Arduino board. Next I set the boundaries of my bed and where I wanted the sensor to check. All you have to do is twist the sensor up and down to adjust how close the hot end is to the bed. After the sensor was mounted, you just plug the brown wire to +12v and the blue wire to ground. The Black wire goes to the signal pin on the z-min endstop. Supposedly you need to solder in some resistors inline (the youtube video below explains it) to lower the voltage being sent to the ramps, but mine works fine without the modification.

Now I never have to worry about the nozzle being to close / too far from the bed...

Here's a great youtube video that helped me get it all setup:

Amateur here, but I've used https://smile.amazon.com/dp/B008FZC8F2 for my 3d printer. This won't work?

I am also using a Anet. the A8[ with this Sensor.] (https://www.amazon.com/gp/product/B008FZC8F2/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1)


I was also [following this video] (https://www.youtube.com/watch?v=G-TwWfUzXpc) But several things didn't work right.


I shall try what you did right now and see what happens.

I'm using the LJ18A3-8-Z/BX that was suggested in this Instructables. The problem I'm having is with the placement of the sensor. I first designed this bracket that mounts on the X carriage above where the filament cooling fan mounts. It fits nicely and is fairly close to the nozzle. The problem is if the nozzle contacts the bed first the whole carriage rotates up. This rotation cause the sensor to lift further away from the bed, which drive the nozzle lower... I'm going to design a new bracket that will attach to the linear bearing block. This will have the opposite effect if the nozzle impacts the bed. The sensor will be driven lower which should trigger the sensor sooner.

EDIT: Also, since it is an inductive sensor the 8 mm range is for steel/iron. The range for aluminum is about 4.5 mm.

Alright, I finally got around to it. My switch is NO https://www.amazon.com/gp/product/B008FZC8F2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 and I changed these settings:http://imgur.com/Sd57MTu

I have my blue wired to the negative(-) on the board, and the black goes into where the red is on the end stop.

Brown (NPN) 6-36v
Blue - Negative on the Anet board where 12v comes in for main power.
Black - wired into the red plug on the Z endstop.

No problem!

This

Look it up on thingiverse, too. Tons of mounts for it that you can print out. You'll see them on pretty much everyone's head.
