Yeah, Openbeam. I'm the guy that assembled all the pre-built machines for the kickstarter fulfillments.
Nice, I've converted all but the mini to E3D V6 Hot ends. I've had the other two machines running the V6 for a couple months now and I'm quite pleased, no more jamming! I had applied a graphene coating to the heatsink of the mini which actually really helped with the cooling/jamming issues but I just got the parts to convert the mini on monday so I'll be doing that soon.
Let me know if you want a copy of my config file or the end effector file (i modified an end effector I found on thingiverse.) It is setup to run 288mm rods with traxxis ball joints (ultibots.com). I wouldn't stick with the original end effector. Terence really tried to get it scaled down but it just doesn't provide adequate cooling.
