Our UM3 has started with this error after a succesfull print of a ABS piece. Right after we start the printer we get a Build Plate Sensor lecture of 192 °C which is clearly wrong. We tried to move this temp with the wheel, with the GCode and with Cura but we didn´t got any results. Also, we check on the cables in the build Plate and in the main PCB and we didn´t see nothing wrong with that. We tried a factory reset too but the error persists, so we think it could be the PT100 temp sensor. Could you help me out with this or give me tests i could run to check if the PT100 temp sensor is broken?
