Hi I am in the process of upgrading to a rumba board. All my temprature readings are off and when I checked the voltage on the thermistor pins it reads 1.27 instead of the 5 that should be there. I have tried reflashing the firmware without any change. It has happened on two different boards one from geeetech and another higher quality one. So it is unlikely that both have the same hardware problem. Can someone here help me troubleshoot this problem?

Have you done PID autotune? Are you printing and the temp fluctuates or drops?
