After upgrading the firmware (to the latest right now) I keep having a problem with getting a connection to my Duet Wifi.
When I remove all power to the board to get it in run mode (after succesfull install and verification) , and reconnect only the main power everything goes the way it should be. But when I connect the USB the board goes into diagnose mode, and there is no way to get it out of that.
I don't know how to fix this issue.
Edit: I might have figured it out. I removed the DuetPanel from the board and it seems to work fine so far.
Maybe it was the panel that was drawing to much current from the board?
