Editing Firmware to allow for Max Bed Temperature to 150C
Hello,
I am trying to increase the max bed temperature of the Prusa I3 MK3s but I am having limited success. I have edited the firmware and changed the variable BED_MAXTEMP to 150C.
However when I flash the new firmware and then proceed to select the temperature to 140C. It heats up but then at 123C it throws an error that says "BED PREHEAT ERROR". I went digging into the code to investigate further on what is limiting me from letting me heat up to this temperature. I found in temperature.cpp that there is a error message that is initiated when isBed? occurs. But I have no clue on how to proceed to increase the limit to 150C to stop this error from occurring.
Has anyone had success with increasing their max bed temperature? If so how?
Otherwise does anyone have any literature that could help me? I tried looking but couldn't find anything.

IIAC, that error may be because the thermistor and associated circuitry reports that the actual heat is not approaching the set point.
