I would like to use two heaters with only one extruder, each one with its own thermistor. I want to reach fairly low temperatures (50ºC - 122F) and I am using RAMPS with Marlin firmware.

How do I have to modify the firmware to achieve it?

... wire the second as 'heated bed' ... and select/use/adjust your thermistors or temp-sensors for lower temps.

I'm mostly using PT100 for heat-controlling applications -- nearly linear from 0 to 300degC, with adjusting for temp ranges usable from -100 to +800 degC winking smiley
