theres a lot of em out there..but my question is..has anyone built one from the plans that are out there and how acurate are they for cutting ribs ect? will they work with autocad? or is there a better CAD program for our hobby that wont kill ones plane budget for the next ten years?
ok..update..I did what U all said and bought a set of plans from

they seemed to be the best design for model arircraft being long and wide enough for most parts needed..(IE ribs..bulkheads ect) so I tosed some money at the paypal godz and few days later in the mail PLANS for my very own CNC router..(cheapest part so far) then came the fun stuff..70 dollars and many hours on Ebay bought me 4 stepper motors and some linear bearings..I have since also bought from hobby CNC a 3 axis controler kit... have scooped a powersupply for the works from a surplus electronics place..my buddy up the road whom is a most excelent finish carpenter is building the bed frame for me(and I reinstalled windows on his computer for him after he decided to go on the web where no man should go..(nudge nudge..wink wink)) and and I have decided to go with a software program called Kcam. it will take a acad DXF file (and other cad program files) directly and controle the CNC router as well..so..now all I have to do is put this whole mess together absolutly straight..without any errors and press the go button..I will add to this over the next few weeks as my trials and tribulations go..wish me luck..
I am doing something similar but it will be for a laser cutter. The Hobby CNC boards work really well, especially for the cost. I built a CNC foam cutter (two of them) and I have been using the Hobby CNC boards for several years now.
I'm talking about the OP who used the hobbycnc plans and electronics. I have this, but haven't gotten around to building the hardware, just assembled the electronics, but haven't gotten any further.
is down right now but I expect that to be temporary.
Here is McMaster's site:

their search feature for drawer slides.
I use the Acme threaded rod and Acme nuts. I use two nuts encased in epoxy in lieu of fancy zero lash nuts. The lash is negligible. My steppers are ball bearing units so there is no need for end bearings.
The drawer slides are used in such a way that lateral twist will not occur. They are used in pairs on opposite sides of each carrier. If you go to:
