As message says... I have switched from RRF to RatOS and everything works, except endstops, which, when connected, trip my smart plug (I think I was lucky with that one).
The endstops are 1st gen, and I remember something about some pins needing to be switched around.
I have attached a picture with the pinout at the endstop side.
I just need to know which pins to switch around at the motherboard end. Currently, the plug is configureed according to the RatOS documentation.
