Guys, I'm curious on any feedback with how to deal with warping on larger prints when printing in PLA? I have a Prusa i3 that is able to make really good prints. However, on larger models, the edges keep lifting off the bed. I've played around with various bed temperatures from completely off to around 60C. Should I increase the bed temperature even more to prevent the lower portions of models from cooling and contracting as much or is there something else I should be looking at? I know in the Cura software there is an option for platform adhesion type but I wonder if there is a way around it without having to enable it?
