3 Thermocouples?

Is it possible to run three MAX31855 thermocouples on a smoothie board?

I will also need ability to set a pin high if a temperature is exceeded on any of the three thermocouple readings. Easy?

To use three thermocouples, you’ll need to have them all on the same SPI port, but with different CS pins.

For the pin thing, you might want to take a look at the TemperatureSwitch module in the documentation, see if that does what you want.

Great thank you. Could you point me to a source showing how to wire up one (or more) thermocouples?

The TemperatureControl documentation has a table : http://smoothieware.org/temperaturecontrol#toc7
