Hello. I am controlling my cnc using ESP32 grblhal and Raspberry PI. I have recently purchased the openbuilds XYZ probe for setting the zero coordinates.

After unpacking the probe and connecting to my controller, I notice a problem that the magnetic clip is constatly shorted to the signal pin therefore my controller "thinks" that the probe is constatly triggered. Does anyone else used this probe and can help me understand how is it supposed to work? Surely the signal and the clip should not be shorted together?
