    Nevermind.  I got an email yesterday and am sending the board and the power supply for them to look at.

    So how long does it typically take for them to respond? I sent them a message late on the 24th with copy to me so I know it was sent. Should I just try and call them?

    I can’t see any problems. I’ll send them an e-mail. Thanks for your help.

    Ok, getting closer.  If I plug in the power supply, the green LEDs do NOT light up.  If I plug in the USB, the green LEDs do light.  

    If I remove the USB plug, then insert and remove the power supply plug a few times, then the green LEDs light up

    So it seems like something is wrong with the adapter, the plug, the socket, or something on the board.  I need to pull the board and look at it under magnification. 

    Oh no errors from Inkscape.  It thinks everything is a-ok.

    I’ve been troubleshooting and haven’t been able to narrow it down since it is an intermittent problem.  Can someone tell me if the following assumptions are correct:

    Following the circuit diagram, it look like:

    Green power LED lights when EBB is connected to the computer (USB) and disconnected from the power adapter.

    Green power LED lights when EBB is connected to the power adapter and disconnected from the computer.

     

    When Inkscape is sending commands to the EBB:

    Red LED lights when commands are being sent to the individual steppers.  The red LEDs will still blink on and off during this process even if the power adapter is not connected.

    The steppers hum when they are active but not moving.

    Like you, I also suspect something is wrong with the power connection to the board.  The plug on the power supply, the socket, or the connection between the socket and the board.

    Thanks for the quick response!  I was going to install it high off the board just in case I had to remove and reinstall.  This saves me the trouble.
