If I can make a suggestion. Perhaps it is just my inexperience, but I print in PLA on a heated bed 60C. I have a hard time getting pieces off the print bed when they have a large surface area in contact with the bed. So I started chamfering the edges of my designs and that has made it easier to get a spatula in to pry off the piece.
Am I doing something wrong with my printing method? I am worried about printing the base plates for this reason.
