¶ Clogging Issues
How to check the clogged part of the printer:
Clogging is a common problem in 3d printing, when your printer can no longer extrude the filaments, you need to confirm which part of the problem
Clogging situation:
When you insert the filaments into the extruder and execute the feed command, the gears on the extruder make a strange noise and the nozzle is not extruded, then there is indeed a clogging phenomenon!
¶ Clogged extruder feed piece
Remove the 2 screws next to the extruder and take out the feed piece.
You can visualize the filament chips in the feeding port, use tools (e.g. 1.5mm hexagonal wrench) to poke them out.
¶ A blockage in the larynx
1.Pull out the Teflon feed tube
2.Loosen the 2 screws of the extruder bracket cover and slowly pull out the fan cable (Note: Do not damage the cable or the port) Take away the extruder bracket cover.
3.Remove the 2 screws holding the extruder in place and move the extruder to one side.
4.Observe the nozzle to see if any filaments are broken off inside the nozzle. When it is not clear if there is filament inside the nozzle, insert a long-through needle into the top of the extruder, press down, and feel if there is too much resistance (filament chips may be adhering to the inner wall)
Circumstances of the blockage of filaments：
Situation 1：
Treatment: Heat the hot end to 250°C, use sharp-nosed pliers to pull out the filament.
Situation 2：
Treatment：
1.Heat the hot end to 250°C
2.Use a lighter to heat the lancet until it turns red, insert the lancet from the top of the hot end, press down and tilt it 30°, and wait for about 30 seconds.
3.Use a pair of sharp-nosed pliers to hold the long through-needle, with the tip of the sharp nipple on one end, and use leverage to pull the long through-needle slowly upward.
If this method works, the filaments inside the hot end will be attached to the long-through pins and be carried out.
Clogged nozzle
Treatment: Heat the nozzle to 250°C, insert it into the tip of the nozzle using the unclogging needle, and then pull it out. Repeat the process several times.
While the above method will fix the vast majority of clogs, in some cases the nozzle is indeed damaged and you can simply replace it.
