    Don't install base marlin, install the firmware I linked.

    where is the thermistor type I guess I didn't type 5 in the right place.
    20 is the PT100 circuit found in the Ultimainboard V2.x
    // 60 is 100k Maker's Tool Works Kapton Bed Thermistor
    //
    // 1k ohm pullup tables - This is not normal, you would have to have changed out your 4.7k for 1k
    // (but gives greater accuracy and more stable PID)
    // 51 is 100k thermistor - EPCOS (1k pullup)
    // 52 is 200k thermistor - ATC Semitec 204GT-2 (1k pullup)
    // 55 is 100k thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (1k pullup)
    //
    // 1047 is Pt1000 with 4k7 pullup
    // 1010 is Pt1000 with 1k pullup (non standard)
    // 147 is Pt100 with 4k7 pullup
    // 110 is Pt100 with 1k pullup (non standard)

    #define TEMP_SENSOR_0 1 //robo
    #define TEMP_SENSOR_1 0
    #define TEMP_SENSOR_2 0
    #define TEMP_SENSOR_BED 1 //robo

    // This makes temp sensor 1 a redundant sensor for sensor 0. If the temperatures difference between these sensors is to high the print will be aborted.
    //#define TEMP_SENSOR_1_AS_REDUNDANT
    #define MAX_REDUNDANT_TEMP_SENSOR_DIFF 10

    //Check for thermistor temerature freefall during the print,
    //This usually indicates that the thermistor has been removed from the head.
    #define TEMP_SENSOR_DISCONNECT_CHECK 1
    #define TEMP_SENSOR_DISCONNECT_LIMIT 10

    #define Temp_SENSOR_0 1 -> 5

    Where is the Thermistor type? I guess I typed in the 5 in the wrong place.

    I am still reading 0 I'm not sure how i am doing this wrong.

    // 110 is Pt100 with 1k pullup (non standard)

    #define TEMP_SENSOR_0 5 //robo ( I also tried #define TEMP_SENSOR_0 1->5)
    #define TEMP_SENSOR_1 0
    #define TEMP_SENSOR_2 0
    #define TEMP_SENSOR_BED 1 //robo

    // This makes temp sensor 1 a redundant sensor for sensor 0. If the temperatures difference between these sensors is to high the print will be aborted.
    //#define TEMP_SENSOR_1_AS_REDUNDANT

    0 is a symptom of an open circuit on the thermistor, the -> was meant to say replace this value with this.

    ok so to be clear it should look like #define TEMP_SENSOR_0 5.

    #define TEMP_SENSOR_5

    Yes, and if you read the resistance of the thermistor (with a meter) where it connects to the RAMPS board, it should not be zero ohms. It should be in the ballpark of 100k.

    #define TEMP_SENSOR_0 5 <- correct

    A simple way to verify is if you flash the firmware I linked, does it read temperature? The tables for the epcos and semitec are very similar so it should still give reasonable temperatures near ambient.

    I've been meaning to make a revision of this firmware for the E3D so I'll do that and upload it.

    Ok If you could just send me that firmware when you get a chance, because when I plug in (below), there is an error when I verify.

    #define TEMP_SENSOR_05 //robo
    #define TEMP_SENSOR_1 0
    #define TEMP_SENSOR_2 0
    #define TEMP_SENSOR_BED 1

    you need a space between the Temp_Sensor_0 and 5

    I tried that also. but I am still not reading a temperature. Just let me know when you have the firmware made, thanks for everything.

    Like I said, temperature is probably an electrical issue not firmware. Try flashing the one I linked before to make sure.

    Ok I will, however I check through my voltage meter and I am getting resistance and voltage.

    BTW I plugged my new thermister into the same plug as the original plug right by the bobbed bolts area. Do you think that could be the issue? I have had good prints with this connection. Screen Shot 2014-10-22 at 1.53.18 PM.png

    No idea, the resistance will tell you.
