If you encounter the clogged extruder issue as shown below, please follow these steps to fix it.
Possible Reasons and Corresponding Solutions
1. Filament issue
1) Unable to continue printing due to exhausted filament
How to Diagnose: Check whether the filament is exhausted, and push the filament detection alarm
Solution: Install new filament
2) Filament extrusion is not smooth
How to Diagnose: check whether the filament is pulled in smoothly.
Solution: It is recommended to install the filament holder in the lower left corner, and make the filament rotate clockwise to reduce the resistance when the wire is pulled in.
3) Filament breaks, causing no filament to pull in
How to Diagnose: Gently pull the filament from the feed port to see if it can be pulled out easily or check whether the filament detection alarm is pushed.
Solution: Reload the new filament after removing the residual filament. For specific operation methods, please refer to the resource below:
Article How-to-Remove-Filament-and-Residual-Filament
4) The wire is not clean, and foreign matter enters the nozzle during printing, causing the nozzle to block and stop extrusion
How to Diagnose: Check whether the filament is clean (it is recommended to store the filament and place the machine away from dusty environments).
Solution: Consider adding a sponge before the filament enters the M5, so that the filament passes through the sponge to clean it, and then enters the device for printing.
2. Nozzle clogged, causing extrusion to stop midway through printing
How to Diagnose: After cutting off the problem filament and reinserting the filament into the extruder, check whether the filament can be extruded properly through Control > Extrude.
Solution:
1) Cleaning the nozzle: After heating the nozzle to 180°C, insert and stir with a cleaning needle, and then manually extrude until the extrusion is smooth. For specific operation methods, please refer to the resources below:
Article:How to Clean the Nozzle
Video:How to Clean the Nozzle
2) Replacing the nozzle: After heating the nozzle to 180°C, use the M6 wrench to replace the nozzle by referring to the resources below:
Article:How-to-Replace-the-Nozzle
Video:How-to-Replace-the-Nozzle
3. The filament slips in the extruder and cannot be squeezed into the extruder.
How to Diagnose: Check whether the filament slip in the extruder.
Solution: Pull out the filament and cut off the problem part, then reinsert it.
4. The heat cannot be dissipated, causing the filament to soften and block the extruder
How to Diagnose: Press the extrusion clamp to pull out the filament, and check whether the filament has an increase in diameter (caused by softening) or blockage.
Solution: Pull out the filament, cut off the end of the filament at a 45 degree angle, and reinsert it. Turn off the printer, wait for the extrusion motor to cool down, and print again;
If the issue persists, please replace the throat cooling fan by following the resources below:

5. Gcode file issue
How to Diagnose: The same file frequently stops extrusion at the same height
Solution: Re-slice and print the model using the default simple mode
