After trying and struggling to get the Marlin firmware to work properly with an inductive sensor (LJ18A3-8-Z/BX) for auto bed levelling. I'm hoping someone can post a known working copy of Marlin that I can take a crack with.

As long as M119 is showing the the sensor is working correctly on the z-min endstop.

The attached configuration.h for Marlin RC6 is working fine on my Wilson II with a 200x300 bed. I'm using a 12vdc relay board with the proximity sensor and using the relay contacts to the RAMPS.
