I can not seem to get past my thermal runaway issues. I ran a print last night that went up 5% every 3 layers. I got to 60% and had a thermal runaway error. I just replicated Gregg's dual profile settings for a single extruder but the print failed on thermal runaway again. I have tuned the PID and set the fan as low as possible but I still can't get past it. Can someone suggest some settings that might help?
