Built based on www.buildyourcnc.com, in conjunction with the companion book.
I know it's been done before, but I wanted it myself.
I have completed about 98% of the physical build. Just a couple loose ends to finish by the coming weekend.
All 3 Axis' are built, and it's very exciting to have to foundation finished. I will be adding the electronics in Feb/Mar of 2011, but Xmas is coming soon. I will be posting video soon once I have the lead screws and bearings installed.
Following this week's efforts I need to dive into CAD (haven't used it before), but I have some time =P
Following this project I have intentions of a 3D scanner, and then the Cupcake CNC machine from www.makerbot.com. Then my prototyping efforts should be complete.
UPDATED 10-3-10
Completed mechaqnical construction. All 3 Axis' are function through their full range of movement.
Posted Video,
UPDATED 12-31-10
Received three of the required stepper motors for christmas, along with the I/O board. I have attached the motors, as well as modified an enclosure to house the I/O & Driver boards.
Remaining = Pwr Sply, Stepper Drivers, Couplings, Router.
UPDATED 3-8-11
Electronics installed, and configured.
Have successfully ran first automation test =)
It's alive.
Now I have to better understand the use of the tool, and the CAD software.
At least it's finished =D

Cool!
I've got a CNC too. mine is 4feet by 8feet and I'm currently upgrading it to a high speed CNC. :)
I use mach3 too

Wow, thats big!
I regret the size of mine to some degree. My car can trasport 2ft x 4ft sheets without hassle. I want to rebuild my gantry and table to mill an entire 2x4 sheet. Perhaps later this summer =)

Great project what kind of
Great project what kind of accuracy/speeds are you able to achieve with this thing? Also has using wood for the base resulted in any warping from temperature or humidity changes?

I would have to double check
I would have to double check the documentation I have as far as accuracy. Speed is meh.
I live in Oregon, so I am a little concerned about temp/humidity using MDF as the construction material. I started the Build in Sept/Oct of 2010, and just finished. After going through the winter, I have not noticed any detrement to it's operation as yet. Something I am keeping an eye on though.
I have to get the full version of Mach3 yet, so I am limited to 500 lines of GCode, but I have been excited by some of the tests I have ran. I snagged some GCode from a blog outlining an R2D2 build using a CNC machine of similer dimension, and crancked out some pocketed shoulders from the legs. came out nice =)

Nice...
Great job! I've build the same machine using the same book. I just posted a blog entry a couple of weeks ago with some photos here. I'm learning about CNC as I go...bought the licensed version of Mach3 and learning how to control the thing...interested to hear more about your experiences....

I totally read through your post before I started. I had been interested in doing the project earlier in the year, but really enjoyed checking out your build before I started.
I have been getting into Google Sketchup, and will be getting the Mach3 software for control as well.
I have to get the electronics yet (Christmas shopping comes first) but can't wait to get milling.

GOOD WORK !!!
Wich type of drives do you plan to use? steppers / servos ?
If you have a specific source for the drives, please, post it.
