RE: unable to resolve underextrusion

Out of ideas. Only thing I can think of is the heat break temperature is under-reporting due to a faulty thermistor. Example, it's says it's 35 but it's really 50.

So 35 to 40°C would be okay for the heatbreak temp, but 50° would be too much? Unfortunately I have no clue what values would be considered normal...

Above 50° PLA will start to soften. What I'm suggesting is maybe the heat break temperature is higher than what is being reported. Just a guess really.
