DuetWifi stopped working

interwebsdesigner

I have my new build with the latest DuetWifi. Everything was fine a week ago, haven't printed since. Started up the printer, worked fine. Started a print and for some reason it was way off center and the head struck the bed when moving back over. I didn't hear the stepper skip but the head stopped and the connection to wifi was lost.

I rebooted and now nothing starts up, I tried going in through repeteir host and nothing. I also have the lcd with it and it just shows all tools now and is non responsive. I tried resetting but have not tried reflashing the board, trying to avoid a reset since I haven't backed up my config.g yet.

Anyone have any ideas other than nuking it?

You can pull the SD card and check it on a PC. You can backup the files that way as well.

If you connect the duet to just USB power does anything light up?

Are there any scorch marks on the board?

No scorch marks. I plugged in via USB and checked serial and it is not showing up as Bossa or Duet. I have tried moving to another usb and can't get it to show up on Win or Mac. I have hit erase several times now, then reset and it just won't show up. SD card was good, so I backed up that. Any other thoughts?

I think it's dead. But it would be helpful to know how it died. Maybe @dc42 has some ideas.

So, couple points I have tried

I have erased the firmware and pressed reset. (note I am not getting any blinking of LEDs)

When I plug in the USB I get a red led on 5v and a green on 3.3v

The diag LED and the USB LED are both red

I tried finding the port once connected on both Mac and Windows. Neither are showing up as Bossa or Duet.

There are no burns/scorches or capacitor issues. Board looks to be in tact.

I have tried multiple USB cables, restarting both Windows and Mac, Samba and Bossa and cannot see the board. To see where the board is I ran ls /dev/tty.* and it just doesn't show up and usually would on USBModem...

Does that help from a triage standpoint?

Is either the processor or the WiFi module getting hot? Or any other components?

interwebsdesigner

No, not anything noticeable on any component @dc42.

Would something like this be covered under the warranty?

interwebsdesigner

@dc42 Any thoughts on this?

dc42

Yes, that's probably covered by the warranty. We will need to examine the board to determine the cause of the failure as it's nothing obvious. Where did you buy it?

interwebsdesigner

@dc42 Great. I purchased it from filastruder. Order #35977. What would I have to do to start the process?

dc42

Contact Filastruder and point them to this thread. They may want to run some tests on your board before sending you a warranty replacement.
