So 60 deg for PLA. According to my big box and octoprint the bed is up to temperature in about two minutes and starts printing. According to a hand held thermal probe placed on the glass itself the bed is 40-45 degrees when printing starts. If I leave the bed stationary at 60deg according to octoprint the bed glass never gets beyond 48 deg no matter how long you leave it. If you alter the bed temperature to 80 deg the glass slowly gets up to 60 deg and not much higher. So question. Is there a calibration facility through octoprint or even on the rumba board itself?
