      Hi,
      I added a physical E-Stop to the system that will cut power to the board and my expansion board. After the power is cut, I want the fans to remain off. Right now they are turning back on when power is restored and the emergency stop is disengaged. Is there a command that will allow me to turn them off and remain off or even reset them to their initial state. I saw the command M911 is to configure auto save on loss of power. Would this be appropriate in this situation?

      I am using firmware 3.4.6 and here is the config file

        @msugar what fans are turning on?
        If they're thermostatically controlled and the temperature is above the set point, they will turn on

          I am not using these outputs for actual fans I am using the fan pins as general outputs for different tools. It is turning on the pins for fans 4-7 on the duex 5 expansion board.

            I actually figured out a solution. I made an additional trigger function and turned off all the tools and rest the machine with the command M999.
