      Hello,
      I am currently using all my 2 pin Out 1-3 and Out 7-9 on Duet 3. I have an additional 3-way solenoid valve which I want to use. There are 3 which are being used on Out 7-9 and I would like to use a fourth.

      Is there another 2pin that I can use to power this? From reading the manual it looks like I can't the VFD/Laser pin due to the control signal being the same for Out 9.
      The only other 2 pins that are not in use are the VFUSED, RESET, and Temp0 pins. Can any of these be used to trigger the 3 way valve?

      Please keep in mind I'm new to using this and our expert is out of office right now.
      Thanks!

        @new_to_me901 you can use out4/5/6 if they are not already in use. Connect the solenoid valve as you would connect a 2-pin fan. You can also use the ps_on pin if you use an external flyback diode across the solenoid.
