It turns out that the quality control on the set screw allowed some screws to be shipped with imperfect heads that trap the filament and prevent it from feeding. Smoothing out the head with some sandpaper and polishing the surface works like a charm. I've successfully done 3 test cubes so far and it feeds like a champ.
I just got notice that my (2) QU-BD units were shipped. I hope to get a dual Hadron running soon. You need pretty reliable extruders to go dual so I hope mine are fine.
Just for fun Jeremy plugged in all the Replicator, speeds and layer heights with an MK7. It produced a nice print, but too slow for me.
This serial #1 ORD has a lot of miles on it and has been to way more hackerspaces than I have. It needs it's own passport

I was part of the pre-order after the kickstarter closed. I met with them at the San Mateo Maker Faire before the kickstarter. I sent them an email last week asking about my order and they sent it right away. I don't have it yet.
They may have been interested in the dual extruder ORD Bot and expedited it.

Thanks. I was in the pre-order batch 1 as well so maybe mine will ship soon. I have everything else for my printer now and just need the extruder to get it finished.
