In the newest release you can define 6 thermistors (5 for hotends 1 for bed). I'm looking for a fix to use TEMP_SENSOR_2 and _3 for other thinks like chamber temp. Installing additional thermistors on RAMPS 1.4 is no problem, because there are a lot of analog pins on AUX connectors. Does someone have a clue how to implement "custom thermistors" in Marlin firmware?
