Jumpy bed temp reading
since yesterday, I experience a jumpy bed temp reading.
Looking at the numbers, it's jumpiung around 2-3 degrees within seconds.
The graphs looks like this when heating up (and stabilzes when finished heating):
Is my thermistor about to die?
Either that, or you have a bad connection in the cable between the thermistor and the Duet, or the thermistor wire is touching something that it shouldn't touch.
"Funny" thing is that is stabilizes as soon as it finished heating:
Exactly when it finishes heating, or when it passes a particular temperature?
I noticed that the jumpyness started at around 55-60C and stopped when it reached the set temperature (85C)
