I just built my own enclosure for my snapmaker and want to add a door switch for laser engraving. So I just wanted to measure which pins of port 4 have to be connected to simulate a closed door, when the door detection mode is turned on. But unfortunately I am not able to switch the detection mode on in snapmakerjs although the printer is connected correctly to the PC and the serial communication is activated. When I try to select the ON state in the settings, it just jumps back to OFF. Did anyone run in the same type of problem or am I just missing an obvious detail?
My printer has firmware version 2.9 and the snapmakerjs software is 2.5.4
Thanks for any useful suggestion!
