Filament not extruding smoothly
My new filament is not extruding smoothly. I usually use Prusament in my Mini, but it was not available in the stores I usually buy from so I got a spool of Creality filament. I have tried purging several times as well as removing and cleaning the nozzle, but it still extrudes in this blobby manner (pictures below). I can hear it too, almost like there are air pockets in the filament.
Any suggestions would be greatly appreciated
TIA

You are hearing moisture boil off in the extruder and messing with the internal pressures.
This year half the issues here have included the suggestion to dry the filament. This one too.
Cheerio,
RE: Filament not extruding smoothly
Well I'll start with a dehumidifier.
I guess I just don't understand how I can go from printing perfectly fine one day with one filament and then the next have drastically different results with the new stuff.
A dehumidifier isn't enough:
Thomas Sanladerer tests filament drying:
After a week exposed in a room with a dehumidifier running there was noticeable deterioration of PLA finish...
Cheerio,
