Pinda probe on SKR 1.4 not working properly

New Klipper user here!

I have a Fysetc Super Pinda probe (three-wire version) that seems to be functioning correctly. I’m supplying 5V to the brown wire, and when triggered, I can successfully read 5V on the signal pin.

However, when I plug the connector into the board and measure the voltage between the signal pin and ground, I only read 0.03V. This suggests there might be a resistor inside the probe board (I’m not too familiar with electronics).

In the Mainsail interface, the probe is always marked as “open,” so it’s not working in Klipper.

Here is the printer.cfg file
