I have set the default printbed temperature to 110C, but when i start the printbed heater the targer value resets to 100C. I can set the temperature to 110 now, and this target is shown on the temperature graph, but the temperature does not go above 100C. The knee on the graph is quite sharp - showing the the heater and power supply are capable of more. Looking at the voltage across the heater it seems to be a duty cycle of approx 80% on.
What am I doung wrong?
