2.3 Insufficient power supply to the motherboard
3.1 Align the upper cover with the cleaning machine and install it correctly before running the curing mode.
3.2 Touch the sensor switch on the back of the machine with your hand and check whether the blue indicator light on the sensor switch lights up. If there is a bright blue indicator light, click the start button of the machine. If the machine does not beep and can run, it means that the machine sensor switch is normal. The sensor switch does not have a bright blue indicator light after touching it, please contact after-sales service cs@creality.com
3.3 Use a multimeter to measure whether there is a 3.3V voltage output when the mainboard sensor switch GND and DOOR DET port are triggered. If there is no 3.3v voltage output, it means the motherboard power supply is abnormal. If there is voltage output, it means the sensor switch is abnormal, please contact after-sales service cs@creality.com
