In this video I add voltage dividers between the X, Y and Z limit inputs of the controller, and the four pin panel mounts for the proximity sensors. I decided not to wire up the proximity sensors in parallel, as they would be for the final CNC machine as I’d like to redesign and recut the plates, and would effect the wiring. To divide the 12v power for the proximity sensors I use 10k and 15k resistors, however according to voltage divider calculators online I can use different combinations. I had received some conflicting advice, and in combination is poor attention while soldering encountered problems with the signal voltage.
