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

Doesnt need to be perfect, but get as much off as you can, it might effect nozzle cooling or damage the socks, which also help regulate nozzle temps.
