Autoleveling is possible with an inductive sensor (LJ8A3-2-Z/BX-5V diameter: 8 mm). But thisinductive sensor needs a metal surface at 2 mm distance so I changed the glass printer bed (4 mm) with a custom made aluminium plate of 3 mm in thickness (dimensions are on the image). This sensor is NPN NO so it does not need any resistor or divider so it works with 5 volts. I have connected the wires directly to the z-axis endstop pins of the ramps board (Brown to Pin1, Blue to Pin2, Black to Pin3).
