Talk:Polyamide

Hey guys!
Just a quick question: I have not printed with Nylon yet but I noticed that the instructions said to print on cardboard AND have the bed heated (to a pretty high temp). Are you supposed to have both the cardboard AND heated bed on? Or should it be to print on cardboard OR a heated bed. A heated bed would not do much through cardboard, right? Or if it did something, it would probably be starting a fire.
Sorry if this is a dumb question, but I was just wondering and trying to straighten that up before anybody tries something incorrectly.
