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?

    Might just be an effect of the circular infill pattern, esp. if done outside in. Try again with monotonic?

      The calibration pattern appears to have a hardcoded top layer. Changing it in the slicer does nothing.

      The calibration page lists some examples which look a lot cleaner. Also, I tried another opened filament that was stored in a closed plastic bag and the blobs are less pronounced. So the third test is going to be a fresh filament.
