Hotend heater fine tuning
-
@phaedrux Before I post pictures, what does this actually mean:
What makes the firmware post this? I'd assume it's that it's seeing different temperature changes even though the heater is enabled for the same period of time, but my M303 temperature plots look good, so what is it looking at that makes it unable to succeed?

It means that the heating and cooling rates didn't settle down to consistent values after several cycles. One possible reason is noise in the temperature sensor readings, which would be apparent in temperature graph. However, your graph appears to be stable, at least in the time scale it can display.
