@dc42 Hey all - finally got time to pull it apart. I replaced the wires with a lower gauge wire and everything works perfectly again. Thanks for the quick responses.
I printed fine last night - I have been running with no problems for the great half of the year. I uploaded a new print this morning to kick off and it gave me a driver error reporting on drivers 0 1 2 3 4 - so I rebooted it hoping it was just a glitch - no. The screen and all led lights are flickering.
First was to check the power supply and that is still staying consistent at 24v - and my lighting LEDs are on. Not sure what the issue could be - couple restarts, reseated power - no luck. See pics please.
As of right now I am dead in the water.
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?
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 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?
