Repetier shows a temperature of about 114 degrees for my heatbed, when it’s actually 18-19 degrees. I have diconnected the NTC resisor an measured the resistance, which is about 110k ohms in room temperature (is this sane?). Ive tried to reinstall repetier and reset the board but the problem persists. I dont really know how to continue searching for the problem, anyone who can give me some leads? Can it be that the electronics are broken?
When I heat the board to approximately 50-60 degrees the temperature shown in repetier raises only a few degrees to about 120 degrees… so some sort of contact with the mainboard there is.
Ive done some more testing and is almost sure there is something bad with the surface mounted resistor. Is it possible to order a few of thoose somewhere?
