Wisps and holes

Hi. I’ve had been having issues lately printing cylindrical objects.

  1. There is a noticeable seam which can be ignored on single items, but when I print multiple items, the seam becomes rough.
  2. The inside of the project is full of wisps. At first I thought the filament was too humid, but even using a new filament straight out of an airtight package, the problem occurs.
  3. Occasionally I’ll end up with small “holes” or pit marks on the eternal wall.

Has anyone experienced this and knows of a solution?

Thanks
