AD8495 with Smoothieboard

by pjwolos on Thu Jan 25, 2018 2:34 am

The AD8495 seems to be at around 120C no mater what I set the offset as in the configuration file for the smoothieboard. When I heat up the block the sensor is in (3d printer hotend), the sensor starts reading down from 120C going in the opposite direction from what the temperature actually is. In other words 30C is actually 300C. Im giving it 5vdc.

If the voltage goes the wrong direction, it probably means you have the thermocouple connected backwards.
