Hello, I'm having problems with the EBB (Electronic Backboard). First off, if I had known they were so sensitive, I wouldn't have installed one; I've already ruined four boards. I've finally managed to connect it to the Raspberry Pi, but unfortunately, the two fans start immediately. I can't turn them off or adjust them in Klipper. If I raise the temperature, the hard end fan runs at 100% and then reduces again after 50 degrees, but it keeps running. I'm completely out of ideas as to what the problem could be. Perhaps a MOSFET (the electronic switch for the fan) on the board is defective, but then I wouldn't be able to do anything anyway.
