#3dprintingproblems To prevent curling, I crazy glued the 1st layer to the tape. The tape lifted off the bed. #cantwin #printrbot #simple
And if you glue the tape to the bed, it will curl the bed with it, right? 
Painters tape is nothing but problems … The best I could get before a heated bed was using glue sticks on glass, preheated with a hairdryer.
gluestick (uhu stic) is awesome with heated bed on glass. pops off on its own when cooled. have to beat it off hot
the best thing I’ve found to avoid curling is Hairspray, aquaNet. ir works justo fine.
