    This simple & inexpensive modification has many benefits over using the glass bed alone. Metal conducts heat better than glass, and eliminates cold spots on the bed. This cookie sheet has a non stick surface which enables prints to come off easily. You will still need to use hair spray or a glue stick, but it's able to be cleaned very easily compared to the glass bed. Bed liners aren't necessary. The surface is smooth, scratch & bubble resistant as long as you use a putty adhesive under it. An oscillating multitool is used to cut it. A wide jaw sheet metal or welding pliers bends the metal corners. A file makes the rough metal edges smooth.

    These thermal scans show the difference between the glass bed, and the glass bed covered with the metal cookie sheet.

    The heater on the R1 is woefully underpowered and just plain crappy. It basically only heats about 67% of the build area and the temperature drop off toward the edges is exceedingly high.
