Hey everyone,

I am currently recalibrating my printer after.not using it for a while. When doing a flow test I noticed these blobs forming in the middle of the circles.

AFAIK these are often caused by moistures in the filament. I already dried the filament at 50°C for a couple hours in the oven and the problem persists. So I guess I should simply get rid of the filament and open a new pack?

What's your assessment?

I doubt a few hours is long enough if the filament is really wet. It probably needs like 24+ hours. I would just switch to the new filament to test if that is really the problem. Then decide if it's worth trying to save the old filament.
