So I have been printing with PETG filament now for a few weeks and thought I had everything figured out….until I started to print some of the larger items. My corners are lifting every once in a while. I do not have the printer enclosed at the moment but I didnt think I needed too with PETG. I am printing on a glass bed with a glue stick layer on it, but has also tied hairspary and have seen similar results Below are the two different settings I have tried and the results that i got:250C Extruder Temp*90C Bed*0.1 layer height*40mm/sCorners start to bend upwards, but its not until I get to about the 1,000th layer that this happens250C Extruder Temp*55C Bed*0.1 layer height*40mm/sCorners start to bend upwards, this time its around the 200-300th layerJust wondering what everyone else is printing at and on in order to get larger prints to not curl. Also wondering if an enclosure will help with the problems. http://ift.tt/1rqTUdn
