    running gbrl on arduino mega and uno.

    When I plug any Arduino into one of my gshields the ioref pin seems to drain all of the power out of it.

    When sending signals to my other gshield all signals seem to be sent to the Y axis and without rotation only powering on. Turning the motors manually still flashes the appropriate LEDs. It recently was working on the uno with source rabbit, but now all fails.

    looking for fixes. Any ideas?

    Thanks!

    Going to try uploading everything onto a due
