Had a call from a customer today having an issue with the Creality runout sensor operating backwards from that it should be.
Found an issue listed on reddit but doesn’t look like a real solution unless you change up the firmware.
I have found out that crealtiy sensor is wired with a black, red and yellow wire. If you depin the black and yellow wires and reverse their order should reverse the operation of the sensor.
Just wanted to post it in case anyone else has an issue.
