Hi, im still newish to Cura, I did have another preference but i found it necessary to switch. I have recently started making my own objects in fusion 360. I was creating a box for a board game im working on, it should be solid but when i import and slice i cant seem to get any infill in the walls. is 1.5mm or 2mm too small? Am i missing something important?
