      Hi folks, after some time I have made the PCB -Duet wiki page.
      But, I am using 24V for my duet2 board, and want to use a 12v separate power source to run the laser. my power supply connections are as per the below picture.

      From that understanding, it seems like already the GND is commoned through the PCB board. isn't it? or do I need to common the GND between the two power supplies?

      Please advise me to clarify my doubt.

      Thanks, folks

        @sarvan Yes, the GNDs are connected through the Duet Header H1.
