I have finished this build, but I will not be going into quite as much detail as I did previously, but some of the things that I did work on/ change were the following:
- Switched over to a 1000w HP DPS800 sever power supply (Over kill I know).
- Re-glued the carbon fibre rods in order to correct for unequal length.
- Added an e3d v6 volcano nozzle.
I would like to thank Richard Horne for designing this printer and releasing a high quality tutorial. His original post about the 3DR can be found here

Hooking up and Xbox PSU to the RUMBA
A reoccurring theme you will encounter throughout this build, is the recycling old parts in the final build. This makes the build much easier and cheaper. One of the first things I started working in the build was hooking up my Xbox PSU to power my printer. After some googling I found this:
I called upon the help of the kind and helpful people over at soliforum.com (shout out to wardjr and elmoret, thanks guys!). I hooked everything up, but for some odd reason power was not being sent to the board. After some more googling I came across some information that there were 2 wires that, depending upon their contract, took the PSU on and off of standby mode. In the end the board was powered on and the hotend, lcd, and fan (the only things I had hooked up) all were functional. The first picture is what the end of the PSU looked like, and the second picture is everything powered up.
More recycled parts
One part of this build requires 6 608zz bearings, and these are common in skate boards and other sports gear. I saw a pair of roller blades that were being thrown out; I thought there could be some bearings inside of them so I grabbed them. To my delight, I found that each roller blade had 8 bearings each for a total of 32 bearings. They were extremely dirty when I got them, but after some cleaning, they all were in good condition. Looks like I will not have to order bearings anytime soon.
My Quest for a Free Build Plate
Since the 3DR is a delta style 3D printer, you need a circular or hexagonal build plate. I did not want to dish out the money to buy one, so I made one with some scrap glass. If you want to do this you are going to need a glass cutter, a cloth, and a piece of wood.
I started by using some hexagon patterned paper, and made an outline. Then I cut it out and traced around it on the glass with a sharpie.

Next I used the glass cutter to score the glass, and along the scored line I snapped the glass alone the line. I used the piece of wood as a straight edge to get straight cuts. The cloth was to catch any glass that may have come off in the process.
Here is the final product:
