Duet conversion of Xinkebot Orca

[whopping pochard]

Our makerspace's modified Xinkebot Orca spent the last few months valiantly printing PPE in my basement, and was slowly accumulating issues. Seeing as I had most of a working Duet2 WiFi recently made redundant thanks to the shiny new Duet3, I thought I'd thank it for its service with a little upgrade before returning it to the space for general use. Primary goal of upgrade was increased reliability and usability, and commonality with our Duet-driven Railcore, along with switch to a Volcano hotend to complement the big build volume.

First thing was designing a new enclosure for the Duet2 Wifi:

Then an enclosure for the PanelDue:

And of course a new hotend carriage for the Volcano:

Still need to dial in print settings, speeds, and feeds, but even with the big twist the glass bed has developed over the years, things seem to be looking good!
