Hello,
I wanted to use proximity sensors as endstops, but the signal out was 12v.
I didn't have any suitable resistors, but I had some 100k pots.
Bare in mind, I'm not at all strong with electronics, I though I'd make a small board to keep it tidy.
I connect the sensors to the pins show as blue/white/red.

Before I connected to the RAMPS, I dialed down the pots to about 3.5v.
However as soon as I connect it to the RAMP power, the x,y,z output is about 6v.
Is the circuit fundamentally wrong?
