Get the mini differential ir sensor. http://www.filastruder.com/collectio...-height-sensor

It works great on my printer with a MIC-6 AL plate for the bed using purple glue stick to get the abs & pla to stick.

I went with a TL-W3M and mounted under the Bearing Mount.

This is a low profile proximity sensor that I have wired to my ramps 1.4 - 5volt power source. This configuration has been working correctly for nearly 2 years without any problems, having the ability to mount the sensor withing 15mm of the nozzle to achieve the most accurate bed leveling. I on the other hand choose to mount the sensor 25mm directly behind the nozzle.

The mount has a adjustable thumb screw to adjust the height easily and quickly with a 3 Position bottom mount screw holes Left, center and Right.
