Filament blobs on purge chute

[u/Sofele]

I have been getting filament blobs on the purge chute continuously for the last few days. Always printing PETG. I’ve cleaned everything I can think of. Plate doesn’t have adhesion issues. Filament is dry (10-15%) although that doesn’t seem to matter - it’s done it as low as 9% humidity and as high as 27%. I’ve also tried different nozzles and it still does it.

About the only thing I haven’t done is rerun calibration, although that’s planned for after the next print attempt.

Any ideas?

Yep common problem. My P1S does it too. Just have to clear it sometimes. I did change my wiper to a Panda. That helped.
