Hello RepRapers,
I built a Prusa i3 rework with MK8 Extruder and printed my first Objects. I am using for my heat-bed temperature measurement a PT 1000 Thermistor / Platin Chip EN 60751. The display of the heating process looks pretty good. But during the print the temperature is jumping (picture). While that peaks the heat-bed is not heating and the temperature decreases to real 80°. What's wrong? My Configuration.h is attached. How can I fix it?
