    OK so something just happened to my R1+ and I am looking for some advice on what could have broken, what needs to be replaced or what in general is going on.

    I finished a print no issues, (60 mins ago) I put on a new print and the heated bed will not warm up but the hot end gets to the temperature just fine.

    if I turn on the heated bed the hot end drops in temp and the bed does not heat up at all.

    I am having a similar issue where the bed is ice cold and reading 80 - 90 Celsius. if I manually put anything over that it will warm up but its definitely off. there is no way I can touch a 100 degree Celsius bed and it just feel warm to the touch. I took the advice of the forum and checked the thermistor and it looked perfect.

    Where this person had a similar issue and it ended up being the board.

    Yes, it is either the wiring to the thermistor or the thermistor itself or ... the RAMPS board. In that order :)
