¶ Problem description
The screen displays "Error, key: 2565, the heated bed is not heating as expected".
¶ Reason analysis
-
Mainboard problem
-
Heating plate wiring short circuit/open circuit
-
Heating plate failure
-
Hot bed problem
¶ Troubleshooting and solution
- Measure whether the voltage at the 2/3 angle of the main board heating cable port is constantly changing during the heating process (the heating process changes normally, and the fixed voltage or no voltage is abnormal). Replace the main board kit if it is abnormal.
-
Use a buzzer to measure whether the connection wires between the main board and the heating plate are normal and there is no short circuit. Replace the cable if there is a problem with the cable.
-
If all the above are normal, measure whether there is a voltage output during the heating process of the hot bed heating wire (220V/110V according to the local voltage). If there is no voltage output, replace the heating plate.
-
Check that the hot bed thermistor and the cavity thermistor are not connected to the wrong position. If they are connected to the wrong position, replace them. Refer to the main board wiring diagram.
