Since my AnkerMake M5C stopped extruding filament, I did some repair work on it today. (Actually, this is already my third time fixing it. There seems to be an issue where the filament gets snapped if it’s left unused for a long time, though the filament I’m using is third-party… so that might be the reason.)
First, remove these four screws.
This is roughly what the interior looks like.
Next, detach the fan and its base from the extruder.
Then, remove the screws on the back of the extruder.
It will look like this. Make sure not to forget the wiring layout; it’s highly recommended to take a note or picture in case it’s different.
Loosen the two silver screws on the lower part of the black circuit board and remove the hotend section.
Pull the green housing off the hotend.
The filament was stuck inside the nozzle, so I pulled it out using tweezers.
Reassemble the internal parts to their original state, and check the condition from the side while slowly feeding the filament. If there is still filament stuck inside the upper guide tube, it is recommended to insert a piece of filament from the opposite side to push the remaining piece back out through the original entry point.
