Anet A8 - hot end temperature still same I've recently purchased Anet A8. First print went well, but now, the hot end temperature stays at ~230&nbsp;°C. When I touch it, it is still cold. I tried the thermistor, and it correctly changes resistance when I blow on it (from 100&nbsp;k&Omega; to ~70&nbsp;k&Omega;). The voltage in connector is about 300&nbsp;mV. 

Does anybody know what could be wrong?
In my case, I had a bad resistor on my board. R41 had only 2.2 k&Omega; instead of 4.7. I replaced it and everything works now.
