Thermal runaways all of a sudden
One of my new machines has started throwing Thermal Runaway errors out of the blue. It's a stock MK3S with the exception of a Nozzle-X upgrade, after which I ran the PID calibration.
Watching this machine print, it seems to run about 5 degrees cooler than the target temp during print jobs, and when I watched the PID calibration it would often overshoot the target temp by 5 degrees, so it seems 'swingy' for the lack of a better word.
I'm fine to replace parts on my own, but I'm not sure where to start. My gut says heater first, then maybe the thermistor, but I'm wondering if it's possible that it's the power supply or even the Einsy board.
Thoughts?

I personally had a bad thermistor lead to thermal run away.

Yeah could definitely be that too, might just replace both I guess?
