    hi there. If your reading zero on the software, then the thermistor is not hooked up (or a very very loose connection). Showing very high temperature while cold is a shorter thermistor, showing 0 (ever) is open (either the black JST connector is unhooked, or maybe from the ramps, or you have a break somewhere between the ramps (control board) and the thermistor itself).

    If the thermister is connected it will at least show room temperature.
    Zero means it's not working.
