I have now :) Very informative :) Would be interesting to see the Kraken crossed with your mini kossel. I'm kinda tempted by a delta, they seem interesting, although I can't get away from the feeling that you're driving a thing on the end of very long arms.
I'm still not sure what I'm doing duet wise. I think I'm almost certainly going to use it on printer 2 which I plan to start shortly. The idea being printer 1 can churn out the parts for printer 2. As I'm designing the basic structure myself I'll be able to factor its size around the dual boards.
I did like what you've done with the wiring though, that's a top idea.
