Thanks to all of you for these contributions., just a few questions.

@RP Iron Man : nice trick with the garbage bag, how hot does it reach inside ? Don't you fear to overheat some components ? Or do you make holes to keep warm but not too hot ?

I was looking at the Printrbot Go v2 and they wrote on their twitter page they wound't do a heated bed due to warping. So I guess from what you all put this is mainly due to the very "open architecture" and could be solved with closing it a bit, that so ?

Anyone using a Creatr Xl or such big volume machine ? Do they have the same issue ?
