My hotend #1 gives me a THERMAL RUNAWAY error every time i print something. Randomly in the print. Sometimes after layer 1 sometimes after 9 hours into a 20 hour print. So just for kicks, I used the same gcode on hotend #2 and it printed fine, all 2.5 days of it. Tech support keeps telling me "oh your fan comes on too fast, or unplug and plug it back in" or something like that. Nope. Still gets the THERMAL RUNAWAY error. I don't even know what that means. Anyway, I just went back to hotend #2 bc I need to get something done (wasted a week and tons of material dealing with this THERMAL issue). Well, now #2 has a new issue - it's not pulling the filament though. It prints what's in the nozzle, but then doesn't advance it as it goes along.
Anyone have any solutions for either of these issues? Seriously frustrated with this thing.
Thanks, in advance.
