Topic: 20 minutes to heat the bed SD2 glass
I'm not sure how long it used to take, but It's 20 minutes now to heat the bed, with 4mm glass (I think), and original kapton tape on the aluminum. That couldactually speed it up, in my mind, since the temperature sensor is under the glass anyway, and glass insulates.
Sides of my printer have cardboard, top is open, room is room temp, heater is stock.
Is 20 min a normal time to heat the bed?
