I am building a printer and using a Rumba control board along with Repetier firmware. I am currently having issue with the thermistor on the heated be being reported as defective by Repetier host. I have tried all the different setting and three different thermistors and it says they are all defective. Anything obviously wrong with the firmware below: Host says : Heated Bed : Temp sensor defect. 1081.75 degrees C // ############# Heated bed configuration ######################## /** \brief Set true if you have a heated bed conected to your board, false if not */ #define HAVE_HEATED_BED true #define HEATED_BED_MAX_TEMP 120 /** Skip M190 wait, if heated bed is already within x degrees.

HEATED_BED_SENSOR_TYPE 7 HEATED

and under pins.h as

HEATER_BED_PIN 9 HEATER

If the Bed temp contacts are broken, would it be difficult to reprogram one of the other sets of pins to work as the bed temp monitor?

I'm not a programmer, in case you couldn't tell.


Thanks.
