Repetier/Rumba heatedbed thermistor issue

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. Fixed numbers only, 0 = off. */
#define SKIP_M190_IF_WITHIN 3

// Select type of your heated bed. It's the same as for EXT0_TEMPSENSOR_TYPE
// set to 0 if you don't have a heated bed
#define HEATED_BED_SENSOR_TYPE 7
/** Analog pin of analog sensor to read temperature of heated bed. */
#define HEATED_BED_SENSOR_PIN TEMP_1_PIN
/** \brief Pin to enable heater for bed. */
#define HEATED_BED_HEATER_PIN HEATER_1_PIN
// How often the temperature of the heated bed is set (msec)
#define HEATED_BED_SET_INTERVAL 5000


Extruder settings that seem to work just fine

#define EXT0_TEMPSENSOR_TYPE 7
// Analog input pin for reading temperatures or pin enabling SS for MAX6675
#define EXT0_TEMPSENSOR_PIN TEMP_0_PIN
// WHich pin enables the heater
#define EXT0_HEATER_PIN HEATER_0_PIN
#define EXT0_STEP_PIN E0_STEP_PIN
#define EXT0_DIR_PIN E0_DIR_PIN
// set to false/true for normal / inverse direction





Pin.h settings

#define HEATER_0_PIN 2 // EXTRUDER 1
#define HEATER_1_PIN 3 // EXTRUDER 2
#define HEATER_2_PIN 6 // EXTRUDER 3
//optional FAN1 can be used as 4th heater output: #define HEATER_3_PIN 8 // EXTRUDER 4
#define HEATER_BED_PIN 9 // BED

#define TEMP_0_PIN 15 // ANALOG NUMBERING
#define TEMP_1_PIN 14 // ANALOG NUMBERING
#define TEMP_2_PIN 13 // ANALOG NUMBERING
//optional for extruder 4 or chamber: #define TEMP_2_PIN 12 // ANALOG NUMBERING
#define TEMP_BED_PIN 11 // ANALOG NUMBERING

I have also checked all of my thermistors with a meter and get reading of about 100k ohms so I am confident that they are all OK. I have also switched the wires for the extruder over to the bed temp hookups and Repetier Host says it is defective too, even though it reads just fine when connected to the extruder temp hook ups.

Stupid question time. Could my problem be that under the Heated bed configuration it spells it:

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.

I switched to Marlin Firmware and Pronterface and now have a temp reading from my heated bed.
I'll switch to some other combo when I am ready to go to multiple extruders.
