I have been using Cura for a while and now IO want to up the quality of my models. Currently to get smooth sides for my prints I use 3 walls. When it gets to the top, the skin layer, I want to learn how I can make the top layers to have only one wall. So the question is how can I get my 3 walls at 20% fill and a 4 layer top with a topmost skin with only one wall? Thanks!!!!!
