Engadget's CNC 'How to'

[joevennix]

Will O'Brien from engadget has produced the first in a series of tutorials on building a CNC machine. It looks to be a small one, with a work area of 3x3 or 4x4 inches. More for routing PCB's. It's very quick and dirty. How accurate do you think this will be? Will it's small size make it a bit more accurate?
Oh yeah, here's the link.

Hi!

Does anybody succesfully recreated the mechanic design?
There are just some clipped and out-of-focus photo.

Im interested the concrete part list, or how the axis are supposed to work. Its really hard to figure out from the pictures.

The first photo shows the use of clear plastic tubing as a flex connection between stepper and shaft, it is too flexible, you can already see it deforming.
Fuel injector fuel line is a better choice, stronger with multiple layers of woven fabric but flexible to take care of some misalignment. And is used by current builders.
