@gloomyandy I found one problem. When I upgraded from 3.3 to 3.4 it erased all of my directories and replaced them with empty and I lost all of my careful printer configuration. I lost days of work so I'm going to take a break from duet for a while.

How did you upgrade? Did you check the SD card in a PC?

@phaedrux I cut and paste each step from the wiki into ssh on pi. when I pulled the SD and looked at the contents I see all empty directories with just a template config.g in sys.

I have reconstructed much of it now. Is there a simple way to generate a backup through DWC? getting at the SD is a real pain in my installation. I don't want to lose it again.

I’m using an external power supply for the rpi. Do I have a ground plane mismatch? Can I power from the duet 5v over the ribbon?

Solved! I put in the jumpers suggested by @Gixxerfast and it works perfectly again. Not sure if it was the ground plane but I'm going to take full credit for that. <pats self on back>

If you're using a raspberry pi, the SD card is not a readable format in a windows computer. The config files are located in the linux file system on the pi.
