ramps thermocouple pins dual extruders (1 reply)

Having problem getting the dual extruders to work with thermocouples.

I hooked up aux1 the positive and negative and pin 3. I get temp readings.

I enabled dual extruders and I tried Aux pin 4 and pin 7 in pins.h section but no luck. I have the LCD screen taking up aux3. I dissconnected one of the thermocouples and oddly enough it displays 2 different readings.


So can i use the Aux2 for the second thermocouple and which pin?
