      After reading that the most recent firmware updates for the Duet 3 made it possible to use both IO_0 and IO_1 for UART communication, I tried using IO_1 to receive serial commands that previously worked on IO_0, but it doesn't seem to work. I also tried connecting the PanelDue to IO_1 to see if it might work and it doesn't work either, although it works fine with IO_0.

      I'm running the most recent firmware (3.2beta4.1). My goal would be to use IO_0 for the PanelDue and IO_1 for other UART commands from a second controller.

      Is there something I'm missing? I believe I added the appropriate lines to the config file (M575 P2 S2 B9600 for my other controller, M575 P2 S1 B57600 for the PanelDue, neither works).

      Thanks.

        I'm curious on this too. I'd like to have my CNC pendant wired directly to the board instead of the panel due

          I confirm that support for a serial connection on IO1 on the MB6HC is not working. I have identified the [first] reason and will fix it in 3.2RC1.

            PS - if you want to test the fix, there is an internal RRF build at https://www.dropbox.com/sh/woso2i7h6k846x0/AADDaKxz3QgiGmKygSMTd00oa?dl=0 that you can try. Use it with caution.

              Both commands with P2?(never mind that was an old post)

                  Is the fix in the latest Pre-release?
