I have a theory/ question to share.
So when I’m printing something relatively small, and god forbid it has a outward slope, it makes a boat like print. It means that the perimeters become taller than infill, like they are from the next layer or even higher.
Later as it moves away from the bed, and the angle comes sharp again, it correct itself.
Could this be becasue they are too close to the heated bed and not cooling enough, thus expanding and smudging or something…?
