I have a 3v3plus and it will almost always throw out an error Filament runout, printing paused, please refill. Thing is I can tell it to forget, and the print goes fine. I have replaced the Sensor, cable for the sensor, Nozzle, gears in the extruder, updated firmware and this always pops up. While it will still print this is in a classroom and causing several issues. What’s left?
