I assume that the orientation of the parts in the .stl files after they are loaded by Cura is the best orientation for printing?
Do I need supports turned on for any of the parts?
I printed the feet without supports turned on and they came out beautifully - almost no stringing and almost no zits on the prints.
I then printed one of the bottom corners, using the same settings and same filament that I used when printing the feet, except I had supports turned on, and this time I had some stringing and some zits on the print.
