I just built my first RepRap (Prusa). I got it working with Repetier and after 2 days my hot end Peek melted :-( . Anyway, my replacement parts come in tomorrow and I hope to be printing again. I just fired up Repetier and it mentioned that an update was available. If I update, will my previous settings be preserved? I am very new at this and would hate to start over if I didn't have to.
