I just finished recording a video between my 12in and my flashforge creator pro heatup time. Both extruder and heatbed on both. It took my 12in 3minutes and 30sec or less to heat complete both extruder and heatbed to abs temp and my flashforge creator pro took 9 minutes to heat complete to abs temp. Ill post a video soon. With a 12v 30A power supply on my makerfarm.
