So I've seen a few threads discussing adding a heated bed to this printer, and I just had a thought. Would I have to do anything other than getting an appropriate heater, attaching it to the right sized glass sheet, then using a high-temp epoxy to attach 4 nuts or similar in the correct spaces to catch the end caps on the metal plate below? I mean anything with the right size hole in the middle would work right? I miss the heated glass bed on my R1, and if it's that simple to add one I see no reason to try to go aluminum. Would painting the bottom of the glass black with enamel be enough for the IR sensor to still work?
