Great, thanks for the reply. I might wait for the release since I had some weirdness when I tried 3.6.0 rc2. I was messing with several things at the time so maybe it was unrelated. In the meantime I have been manually checking my config into github. 
Thanks again and I look forward to trying this out.

This is great, thanks. But right now when I try to install the plugin I get the error:
"Failed to install package opencv-python, package manager exited with code 67"
Any guidance?

Duet 3 Expansion TOOL1RR TOOL1RR 3.5.4

Duet Web Control DWC 3.5.4
Thanks
Just to let others know, I was having the same problem as the OP. I had to force the update of the firmware using the instructions linked above using the BOSSA method and a connected Pi 4. Once that was done the board was connected and the web UI showed the tools and axes in the dashboard.
Thanks everyone.
