I've learned of another cause to this problem - a loose Thermistor wire. In the video the white wire going to the hot end is the Thermistor wire. It's kind of loose and zip tied a few inches up. My hot end was getting temperature variations (up to 10 degrees in a second) and sometimes would still do a Thermal Runaway error. I've just zip tied the wire to my blue filament tube as close as I could to the hot end and fairly snug, as well as zip tying it a few other spots to keep it more steady and consistent. Temperature is holding solid and not fluctuating at all now. I thought the screw holding it in place on the hot end would be enough but apparently not.
Just a heads up, I also had a problem where my printer would loud beep and reset mid print. I believe this was a different issue of a wire being loose. Took out the main board (I have the silent board upgrade) and redid all the connections. Gave all the wires a little wiggle and shake. Everything solid. Prints like a charm now.
im gonna try this tomorrow i also got the e1 error and after replacing the termis it dont keep it steady it gos up and drops down and gos down to about 160c i beleave and then gives the error
Let me know how it goes. Mine is finishing my prints but not holding as steady as I'd like. I think part of it is how the Thermistor wire moves as the nozzle moves around and I need to secure it differently.
