Duet 3 6HC dead, I is sad (fixed!)

Interesting... the green network LED is blinking now... huh.

This worked as well. Confirmed that the PanelDue was NOT connecting, entered the above string, and it connected.
What does this all mean?

@kb58 You asked, "If you pull the SD card and put it in a PC is the file system still intact?"
Yes, there are a ton of files in there. I haven't messed with the SD card or added anything, but yes, the file structure seems normal. Not sure to go from here, but a huge THANK YOU for getting me out of the worst of this mystery.
Rebooting the board (unplugging the USB briefly) confirms that the ports are back to not working. Should I manually reenable and refresh config.g?

Power off, pull the SD card and check it in your PC. It sounds like the SD card either isn't being read, or it doesn't have a config.g on it.

Check if config.g exists in the /sys/ folder on the SD card.
-
@phaedrux yes
-
@kb58 Oh now this is interesting... zero file size.
-
@kb58 Fixed!!!!!!!
Deleted config.g and renamed the backup to .g, and it's all working again. Wonder how that happened, but regardless, a huge thank you, phaedrux!
-
Take a backup of your sys folder !!!
-
@kb58 For anyone else who has their controller freezing up immediately after editing config.g:
Apparently the existing file on the SD card is first erased, and then the edited file takes its place. If the write fails, the controller has nothing to fall back on, so config.g has to be rewritten via other means.

That’s not quite right. If there is no config.g, the firmware will try to execute config.g.bak. In your case, there was a config.g, it’s just it was empty. So it didn’t execute config.g.bak.
