I have an Ender 3 v3 se with stock firmware (1.0.6 iirc) and am running Octopi on a Pi3b
I am trying to add a Creality filament runout sensor.
I have mounted the sensor on the gantry but would appreciate some help on connecting it up.
If I plug it in to the printer, will the printer tell the Pi to stop the printer?
Or if I connect the sensor direct to the Pi, where do each of the 3 cables go on the Pi pins?
