Just bought a Ramps 1.4 and wired in an Adafruit MAX6675 breakout board to the SPI on the Ramps. Using Marlin firmware I did what I thought was the necessary commenting of config.h with no luck. Do I have to do more in the firmware to get the MAX6675 to work with Ramps? I know that the SPI is suppose to be used for the sdcard but I would rather use the parts I have on hand than waste more money on this project. Any help would be appreciated.
