I have an early, much upgraded printer. Had some issues with prints detaching and warping on the bottom. In my searching one of the things mentioned is uneven bed heating. Always wondered about how this bed and heater look a bit "home made": held on with what looks to be metal "duct tape" and a good few inches smaller than sides of the bed. Never bothered to research it as "it seemed to be working fine". Now, not so sure. Are there visuals of the bed heater, as attached? Is the heater supposed to cover the entire bed area, or is "conduction" relied on?
