Geeetech a30 records temperatures of - 19 or lower temperatures than the real ones, causing the hotend to heat up more than is due to change the thermistor but the fault continues thermistors are tested on an arduino plate plus ramps and there they work Well, it is possible to use another pin to connect the temperature sensor and update the firmware?omegle xender

Hello, if there is no problem with your thermistor, it should be a circuit problem. You can check whether the circuit is broken.
You cannot solve it by changing the pins and updating the firmware, because the firmware of a30 cannot be changed.
