I'm trying to make a 3d print, but ultimaker cura is automatically enabling Adhesion. I turned it off, but it turned on skirt. I know the point of skirt is to get some filament out before the main print, but my printer is a FLSUN v400, which already ejects some filament before the main print, so I don't need an extra skirt. How could I turn off Adhesion and skirt/brim?
