So I have an MKS Sbase v1.3 that I am trying to use in a delta printer. I am trying to use a PNP inductive sensor with it and it doesn't work. I have tried using a voltage divider with it already (10k ohm and 15k ohm) but it doesn't give any signal when the probe is triggered. Can anyone help me?

P.S Yes, I do know that the board has physical pullups. I am thinking of using NPN MOSFETS but I don't know how I should wire them.

After testing my z-min endstop pins, I found out that I could trigger the probe manually by using a jumper wire between Signal and Ground. I then used a NPN MOSFET to connect the sensor to the endstop by connecting the black wire of the probe to the base, the signal wire of the endstop pins to the collector, and the blue wire from the probe and the ground pin of the endstop connector to the emitter of my MOSFET. Note that my mosfet is a TIP120.
