¶ 1. Determine the location of the noise
¶ （1）Fan noise
¶ （2）Synchronous wheel noise of shaft motor
¶ （3）Optical shaft and slider noise
¶ （4）Extruder noise
¶ 2.Preparation tools: grease, hexagonal wrench
¶ 3.Steps for troubleshooting
¶ （1）Fan noise
¶ (a) Check if the noise is caused by a deformed fan. Press both ends of the fan manually to make sure the fan is not distorted
¶ (b) Click "Turn on the fan" on the PAD page, if there is still noise, you need to replace the fan
¶ (2)Synchronous wheel noise of shaft motor
¶ (a) Disassemble the noisy shaft, remove the motor, and refasten the two screws on the motor
!
¶ (b) Fully lubricate the motor bearings with grease
¶ (c) Remove the yellow shims and bearings from the motor to observe if there is any effect
¶ (d) Adjust the belt elasticity, check if the belt is stretched or deformed, and make sure the three belt elasticity is the same

¶ (3)Optical shaft and slider abnormal noise
¶ (a) Make sure there is no obvious resistance when sliding the slider, and use grease to fully lubricate the optical axis and slider
¶ (b) If you find the optical axis loose when sliding, follow the steps in the video to apply glue to fix the optical axis. If there is no effect, please contact after-sales service

¶ (4)Extruder noise
¶ (a) Check if the noise is due to extruder clogging
After loading consumables, click "Extrude" to see if the consumables can be extruded normally. If it can't be extruded normally, clean up the clogging and click "Extrude" again to see if there is still a noise.
