Looking at how the wires are plugged in, you might be on to something here. The extruder stepper seems to be wired into the same port as the breakout board that the thermistor is connected to. If that is the problem though, any ideas how can I fix it and why it's only showing up now? I've had this printer for maybe 2 years now and I installed klipper on it last month, but this issue only began a few days ago.
