I finally got a replacement motherboard after 4 weeks of back and forth with about 3 different people. Put the new motherboard in and the nozzle just plunges straight into the center of the bed and keeps going. I’ve checked and replaced the sensor on the left side of the tower, that doesn’t seem to be the issue. The blue LED that is only supposed to be lit when the nozzle touches the bed is lit all the time. Even when I unplug the strain gauge. I’m guessing something in the little adapter board that’s mounted on the nozzle got fried when the motherboard started on fire. I also lost an SD card to the fire, the card that was plugged in when the machine went down is not responsive anymore. Has anyone had this issue yet and know of something else I can check?
