29. How to clean a nozzle on Ender 3?
May 2, 2021
There was a time when cleaning the nozzle with the nozzle cleaning needle did not clean the nozzle perfectly. Eventually I ended up replacing the PTFE tube and the nozzle.
Here is a video I found very helpful from Creality. It helped a lot.
Also, check out the video below that explains how to remove the nozzle without skipping the video frames.
Hope this helps!
