As said on the title, I can't get clean prints on curved printings from in to out (in the picture the piece is upside down). So, when I print pieces with round borders like the one on the picture, the curve at the bottom of the piece, it prints it like the one shown on the first picture, while the curve at the top of the piece (second picture) is printed perfectly fine. I tried to print both with and without supports, but same results at the end. The only piece that gets better with supports is the central piece. It doesn't get perfect but I have to say that it improves a lot. I also tried to print the piece in vertical but the bottom layers are having the same results, so I don't know what else I can try. Any advice?
