    Quick Q...

    I just managed to break one of the wires into the thermistor under the heated bed. I have a few spare Semitec 104GT-2 thermistors as used in the E3D extruders, will they work as a replacement?

    Thanks

    They should. The only difference may be in the firmware thermistor type (I don't remember looking at that closely).
    If the type is incorrect the readings will be less accurate. I know where the thermistor type was set for the hotend, I think there is probably one for the heated bed as well.

    Will give it a go. Just need to find some heat resistant glue now.

    Yea, it is same:

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


    The last line there, just change that to the thermistor type you are going to use.

    (this is configuration.h--same as for hotend type changes)

    High temperature RTV (from an Auto Parts store) will probably do the trick.
