toolhead pcb: endstop & probe don't seem to work on Octopus Pro

[piotrb]

I have my XES wired directly to the switch NO leads ..
And I guess the Bat45 circuit effectively accomplishes the same with the probe (it becomes a NO switch to ground)

Not sure what's going on .. it seems like if you just bridge the gnd/signal leads on the octo pro .. it isn't enough to trigger that endstop .. I can't seem to get it to work .. I tried pull up, pull down, negation configs in klipper on that pin and its just not reacting to the switch.

Strangely, when I connect a multimeter between the pins (in beep mode) to see if the actual path is being bridged, the switch/probe start triggering as expected .. what am I missing?
