I figure it is about time for GUS (Geared Up Simpson) to get his own thread. As of today, as far as I am concerned, he has arrived. He can consistently (calibration between every few runs may be needed) make big beautiful prints.
His first print.
Movement demo.

Congratulations! This is indeed a milestone in the Simpson evolution.

Not only that, but there will shortly* be at least three more GUS Simpsons out there, testimony to how much we all like cool printers with gears and waving arms 
I think that rate of adoption says a lot about the promise of the design.
* shortly == just few days, perhaps even this weekend, at the rate people are going. Two are already moving and just need calibration to make test prints, another is waiting for vitamins. Still more are at earlier stages of progress. . .

From what I have read on the Reprap forums it's never been done before, you'll be the first to print a round spool!

No worries! I am slowly adding all the necessary information to my GitHub.
The only thing that is really important is that you have the M8 holes located on the verticies of a equilateral triangle with 250mm sides. (You can actually change that dimension. Smaller=Bigger Work Envelope. However, the bigger work envelope starts to get harder to use for standard parts.) It is also important to have room for the shoulders to rotate through 60 degrees. Other than that you can make some fun shaped GUS beds. I just happen to like constant width shapes.
The work envelope will get wider and taller the closer the shoulders are together. However, you start losing the area behind each shoulder.

Every day I'm shufflin'
The base is just a hand cut job. I'm hoping to get a CNC cut MDF base made any day now. Anyone know where I can order a basalt base like I see on all the other GUS's? If I can't order a basalt base I'm going to see how badly my tile nipping skills have deteriorated and cut up some sort of a tile. I don't know how well a ceramic tile will function as a heated bed. I'm guessing quite spectacularly badly; might be fun. :-) Except for that and the limit switches, which are in the mail, I think I have everything. Now it's just a race to see what I break first as I learn how to use it.
