    Cr10s Pro incorrect temperature readings

    Hi, I have a Cr10s Pro and my printer says that my nozzle is 216 degrees (C) when it feels warm to the touch, and my hot bed is extremely hot and my printer says it is only 26 degrees (C). Please help

    It sounds like you could have the bed and hot-end connectors reversed.

    Check the the wring and make sure the wires calves are labeled correctly

    I should say that it was working fine, but then my nozzle got clogged and as I took the nozzle off to unclog it, the temperature of the nozzle suddenly went from saying it was like 46 degrees to 216

    As most thermisters are 100k at room temp I would measure your thermister at room temp
    Below is my 100K Thermister Chart.

    See attached chart

    https://www.makeralot.com/download/R...-3950-100K.pdf

    At room temperature the resistance of my thermister is R25?C=100KΩ?1%
    At 216C my thermister is R216?C=464.5Ω?1%

    Lookup the chart for your thermister and measure the resistance at room temperature an compare to the Lookup table.
    I too have had what I believed was a good thermister dissembled the hot-end only to find the same happen to me.
    Replaced the thermister problem solved.

    Ok I'm not exactly the smartest when it comes to wiring, so I have no clue what any of that means but how could the thermister just all the sudden stop working properly?
