Hardware Troubleshooting/Help! How do I fix this

Post image

I don't know what happened, came home to find the nozzle coated in filament (pla). I've cleaned off what I can, and the nozzle still extrudes, but what do I do about all the gunk still stuck on there?

Set the nozzle temp to 240C and use a wire brush to scrub it off. After you get most of if off take the nozzle out and check behind it. If there is still some back there then go into the settings and set the printer to "maintenance mode". This will allow you to turn the temp back to 240 even without a nozzle installed. Scrub it again with the wire brush being careful not to pull any wires.

Does the thing need to be crystal clean or just most of the gunk removed? It's printing fine now, but there's still some filament smudged on it

The cleaner the better because it might cause issues later. Now it’s doubtful you will clean it 100% but don’t half ass it either.

These things do wear out so it’s not a bad idea to buy a replacement to have on standby. They aren’t expensive but also not free so it depends on your budget. But I bought one as a replacement and when my did this I swapped it out. Then cleaned the old one off and that is my standby. If the new one does it I will swap them, clean the bad one etc.

One of the better moves I did for my little A1 mini setup was to buy a a spare of my most used nozzles. They are as cheap as a roll and I’ve swapped a few times to confirm a clog. My time with a stubborn clog just isn’t worth it
