don't worry, just the 2 rolls of filament (polyplus pla) that i had were bad... bilby3d stuff works fine EDIT: that's not it. with the bilby i was trying to print at 210˚, but it would only preheat at 220˚... i think that the rafts that started at 220˚ and the part being 210˚ was what made it work... anyone have any ideas/support for me?
