DIY Desktop CNC Machine for $400

DIY Desktop CNC Machine
http://www.kickstarter.com/projects/...op-cnc-machine

"A modular, inexpensive, versatile desktop-scale CNC machine to put computer-automated machining and fabrication in the hands of creators. Whether they be hobbyists or evil scientists, small-scale manufacturers or budding inventors, the power to go from on-screen design to precision-machined product in a few mouse clicks is very exciting."

"This project will result in a finished, new, well-designed CNC machine that will then be made available in kit form at several different project entry points. From well-documented and comprehensive plans and construction manual, through electronics, motor drive and chassis kit combinations, to fully-assembled systems, there should be a solution to fit any skill-level and/or budget."

This appears to be a very cool tool and would be ideal for prototyping smaller parts (Axis Travel: X = 11"; Y = 8 1/2"; Z = 3 5/8"). A metal base is an option.

DISCLAIMER: I, nor anyone I know, have no personal interest in the project but thought that there would be people here that would be interested in it.

Looks like 3-Axis to me, X, Y, and Z are there. X is in the base, Y and Z are in the overhead.

Needs to be three times that size and I'd be interested, get the X and Y to 24" x 36"

And which also has WAAAAAY too much wobble in the "spindle"! Fasten a dremel down solid and it will beat a tool to death in seconds because of the run-out in the spindle that causes any tool installed to wobble quite a bit, it should run smooth but dremel tools do not.

True, if anyone has ever taken a Dremel apart for cleaning you will find it's two main bearings are supported in flimsy rubber sleeves that allow lots of movement.

The main difference between a "good" rotary tool , or die grinder, and a cheap one is how much the stone or burr wobbles while running. Most cheap die grinders will destroy a carbide burr in short order because of run-out causing it to bounce and there simply is no comparison between a cheap die grinder, air or electric, and a quality tool as the quality tool is so much smoother it is amazing-this is one tool NOT to pinch pennies on! IMO Dremel tools are an over hyped joke and are no better than the cheapo HF types, they may last a bit longer but a $90 Dremel will still have just about as much run-out as a $9 tool. Just compare a CP ( a REAL Chicago Pneumatic), Snap-On, etc die grinder with one of the $10.00 wonders out there and the difference while running is very obvious still most guys will buy those cheapo rotary tools and brag about how long they last, never mind they run like $#^% and destroy burrs and stones at an alarming rate.

That is only good for working on styrofoam and other soft materials. No way could you use it on metal.

I already have a router table, also ,it'll cut aluminum just fine ,no computer just a template is needed...
I dont see any plasma or water jet so what good is it??? that dremel tool wont last five minutes.Besides you would need lubicante sprayed on the bit..it sounds like a dream, I'll have to see it to believe it..plus the guy dont look like he could pound a nail and probably shouldnt be around machinery.
