So I printed this using PLA at 200 degrees with the bed at 65 degrees. It all went pretty well but about 2/3 of the way through the corners began to peel up from my glass plate. Can anyone offer thoughts as to why this happened? I know a certain amount of warping is to be expected but this makes the linear bearings on the back sit out of alignment and the carriage drags. Any thoughts on how to remedy this?
