What problem are you trying to solve? If it works fine don't try and fix it!Hello, has anyone updated their Ender 3 v2 to the latest version on Marlin? If so, how did you do it? Did it make any difference?
I agree that sounds more like the temperature sensor is not working or disconnected.I get the 'runaway temperature' message and a lot of warning noises.
Cleaned the hot end, new nozzle, new PTFE Bowden, just waiting on new silicone sock/boot thingy.
It does shut down when it happens.
I may be approaching this from the wrong direction, it could be the hardware not the program.
