Duet 3 + SBC Lost connection. No Header
-
If you can still access the configuration files from the Pi you can use those same config files on a separate SD card that will then go in the Duet. You'll also need the DWC files present in the www folder.
Here's a breakdown of the SD card contents required.

Would most likely want to add
M552 S1to enable network for stand alone (if not already in there ofc, but it's not needed for the Pi) -
@Phaedrux I managed to get a M122 report eventually, it was very difficult as you see the board is resetting every fraction of a second. I have checked continuity on the reset button and it is open so should be okay. :

Looks like it was the SD card. I made a new one (for the PI, not standalone) and now it all works.
Not sure how to mark the post as solved, thanks for all your help!

Glad you figured it out. I wouldn't have immediately thought of the SD card.
-
Do you still have the SD card that didn't work? My suspicion is that you had a bad command in config.g and the firmware was failing to catch the resulting exception. I'd like to fix that.

You are absolutely right, it was an error in config.g, I was setting up an end stop and the software advised me I had to reverse the pin, or something like that. I looked up how to do it and needed to put a "!" in front of the pin number. From memory it was something like
M587 Z0 S1 P"Io_2"
so I stuck the ! before the P like:
M587 Z0 S1 !P"I0_2"this totally trashed the setup, how do I know? I did it again!
It should have been
M587 Z0 S1 P"!Io2"Forgive me if the syntax is wrong but I am not a programmer, anyway it worked this way round!
-
@chrishornby ...and sorry, not got the card, I re-flashed it, but didn't need to do so as deleting one character in the config file would have fixed it!

@dc42 I am wondering whether you received my first board and whether you need a AOZ1284 as I have one in my possession
