Ramps 1,4, 24V PSU, modified the D1 diode and changed polyfuse to work with 24V,
Z probe is a NPN inductive sensor, wired the brown to 24V, the blue to ground, and added a diode to the black and attached tothe S on the endstop pins.
Was working fine, then randomly it started always triggering high.
The problem I am facing is that I have switched ramps boards, switche npn sensors, and still no trigger. I get a led light on and off when I am close to the bed, but Repetier host does not recognize it as a trigger m119 returns Z-Probe_State : High always. Pulling my hair out because it was working just fine and was easy to install, now for some reason I cant get it to work at all.
EDIT: Just changed #define Z_PROBE_PULLUP 0 to #define Z_PROBE_PULLUP 1 and I get a constant Low signal, wont trigger to high.
