I'm using Cura for Robo and running the recommended (non-custom) PLA settings for my prints. I'm selecting the light fill. I'm noticing Pillowing on the top of my print. similar to this. It is only in a certain area that it happens on one specific print, which would be the biggest area of infill for the part (makes sense). Most of the other areas consist more of edges, so there is very little infill going on. Almost everything is close to a solid fill because the walls are so thin. The reading i have found says there are typically a few ways to resolve this issue; increase the fan speed on the top layers, increase the number of top layers, and possibly increase or reduce the fill density. Has anyone else had this issue with their prints and if so, can you make any recommendations on what changes should be made to help my cause? I'm new to Cura for Robo, because I was using the MatterHackers software on my R1+. I was hoping to stay with the recommended settings as much as possible without futzing with the settings if possible. But, with 3D printing, I know that changing the settings based on the part being printed may ultimately be the answer, since all 3D designs could exhibit different problems based on the shape, size, etc. I poked around in the custom settings, but I couldn't find a setting for the fans for the top layers only. Thanks in advance.
