Additional Temperature Sensor

  • Hi Guys,

    hope someone can help me here. I am trying to connect a third party heated bed. I am Using FW 2.5.3. The heated bed is already working. What I cannot get to work is the temperature Sensor. I am using a 100 kOhm Thermistor. Unfortunately all settings I am trying to apply to the FW don't seem to work.

    As soon as I connect the sensor to the 5 pin connector, the printer doens not longer activate the heated bed via the heated bed manager. When I try to use the temperature sensor connector for the 2nd extruder It is also not working. It constatly shows 30°C even if there is no sensor connected. All settings I try to apply to configuration.h result in noting.

    Any suggestions on how to implement the sensor? Where do I have to change the values?

    I modified pins_BQ_zum_Mega_3D.h so It will use the sensor port for the 2nd Extruder. like this but nothing happens:

    #define TEMP_0_PIN         13  // Analog numbering: DIO67
     #define TEMP_1_PIN         14  // Analog numbering: DIO68
     #define TEMP_2_PIN         15  // Analog numbering: DIO69
     #define TEMP_3_PIN         -1   // Analog numbering: DIO62
     #define TEMP_BED_PIN       TEMP_1_PIN    

    and also assigned a sensor to the configuration.h like this:

    #define TEMP_SENSOR_0 99
    #define TEMP_SENSOR_1 1       
    #define TEMP_SENSOR_2 0       
    #define TEMP_SENSOR_BED 0

    and also like this:

    #define TEMP_SENSOR_0 99
    #define TEMP_SENSOR_1 0       
    #define TEMP_SENSOR_2 0      
    #define TEMP_SENSOR_BED 1

    does not change anything...

    Suggestions highly welcome. Thanks
