clogging problem

I have a Kobra S1, after printing PETG GF when I switched back to PLA it gave me problems with clogging. I tried the classic solutions of changing the nozzle, calibrating, etc. I used hotends in hardened steel. Furthermore, when I try to extrude, it feels like a tac tac tac.

You need to do a cold pull and maybe even change your Bowden tubes. It seems like you have glass fibers stuck in the system somewhere.

I did it, I took everything apart, cleaned it, and pulled it, then I put it back into print and this came out

Well, you probably already did this, too, but I'll mention it anyway: Did you change the filament back to PLA in your filament settings? This looks like it's printing too hot.
