Has anyone ever looked into putting some cooper or aluminum tape between the bed heater and the glass to try and even out the hot and cold spots? I did a search on the forums but nothing like this hit. Maybe the 6 has a more even distribution of heat but I remember seeing thermal images of the 5’s bed and it is kind of wonky (http://www.sd3d.com/not-all-heated-beds-are-created-equal/).
