¶ I. Nozzle heating abnormality
¶ 1. The nozzle does not heat up
¶ (1) After clicking "heating", check whether the red light of the corresponding mos module on the motherboard will be on!
¶ (2) Check if the corresponding sockets on the motherboard and adapter board are loose or detached!
¶ (3) Measure whether there is voltage at the ports of the motherboard and the adapter board, and whether the voltage is normal.
¶ (4) If there is no abnormality in the wiring then replace the temperature sensor and heater bar for testing

¶ 2. Rapid cooling of nozzle
¶ (1) Check if the silicone sleeve is on the heating block, and if the nozzle temperature sensor and heating rod are loose.
¶ (2) If there is no problem in the above troubleshooting, then replace the temperature sensor and heating rod for testing.
¶ II. Abnormal heating of hot bed
¶ 1. Hot bed does not heat up
¶ (1) When clicking "heating", check whether the light of the mos module corresponding to the hot bed in the upper case and lower case is on, if the light of the mos module in the lower case is not on, it is judged as the mos module is damaged, and you can contact the after-sales service for replacement.
¶ (2) Check whether the positive and negative wires of the heat bed are loose or detached.
¶ (3) Check for false soldering on the MOS module
