External Thermocouple board & RAMPS
Posted: Sat Jun 08, 2013 11:08 pm
I am trying to get the External Thermocouple Board 1.0 running with RAMPS and I can't get it running right.
I am using:
http://reprap.org/wiki/ExtThermoCouple_1.0
I hooked it up to my RAMPS 1.4 according to this diagram:

I set the appropriate configuration.h and pins.h lines according to this section:

Yet, I get a reading of 480C for room temperature. The my multimeter reads the signal output voltage of ExtThermoCouple board in the 200-220mV range, which I interpret to mean 20 to 22C, which is about right for the room. I've tried this on RAMPS boards of two different makes, and with an Arduino Mega and a Taurino Classic, to the same results.
I haven't found any other resources to help me resolve this issue in making it work.
