Hi, How to display the temperature above LCD？
you can measure the resistance of the thermistor on the motherboard and the resistance of the hotbed.

The temperatures on the LCD are like when the printer is switched on: the order of the nozzle and the heating plate are at 0 but I can see the temperature. There is just the message below "heating done" instead of "A20M ready".

Okay but start measuring and I have to look for what?

thank you

Hi, you can measure whether the power supply output voltage reaches the rated voltage; then check if the wiring is intact and the wiring may be poorly connected or damaged. The resistance of the heating cartridge is about 3.6ohms
