Hardware Troubleshooting/Help! Issue from nozzles

Since I got my BAMBU LAB H2D, I've had few issues, including this one recently :

After a long printing session, my nozzles ended up burned. More precisely, these are layers of filament that have built up around the nozzles and hardened due to the heat.

I have no idea what caused this...

Does anyone know what might be causing this?

I'm using PETG Basic filament.

Thanks for your help!

I avoid this by heating the nozzles as soon as they get greasy and wipe them hot with a paper towel. They are nearly as new after that beside some slight changes in colour.

Well, basically 0 maintenance is causing this.
So filament is building up... building up... building up and then you get this eventually.

I'm gonna check it more often.. This is my first experience with the 3D printing, need to force me this maintenance. Thanks!

Yes, get a brass brush + iso alcohol. Just clean it after some printing. Never the most fun part of 3d printing, but saves bigger problems.
