I just went through and did a quick test - for circles and Arcs in parts Alibre will export the drawings 1:1 into DXFs maintaining circles and arcs. As you get into more complex geometries I cant guarantee that this relationship will be maintained. Let me know if you want me to shoot you a sample dxf or if you have something you want me to model and dxf out.

Awesome, thank you. I don't have anything specific in mind at the moment, but it's good to know that at least one bargain priced bit of software doesn't "cheat" with curved sections.

Now all you need is a waterjet.

I made a cube paperweight once, has the typical pocket on all faces and then you go in with a dovetail and machine out the ID at the bottom of the pocket and the remaining material falls.

Fun little object of conversation.

The router attachment you are using could be used to make homebrew pub signs

Ah hell, I've been looking at mini mills for a while, now to see you can CNC it, I had better pretend I never saw this thread or my want will outpace my need.

OK, this is pretty cool. Was it difficult to build?

I have a pile of steppers pulled from some old laser printers waiting for a project like this.

It wasn't very difficult to build at all. This is one problem that definitely has money as a solution.

I did some of the work myself, but I used a few kit components that made the build fairly easy. For another $1,000, I probably could've sourced all the parts from one supplier, ensuring that the project would be easier to build than some Lego kits. For another $3,000, I could've had a complete machine.

On the other hand, I could've spent half what I did, but I'd have pulled my hair out doing the engineering by myself and manually machining parts on a substandard mill.

I highly recommend using parts from CNC Fusion to get a workable foundation upon which to build.

For something smaller but far more homebuilt, look up RepRap. The work they've done translates well to CNC applications beyond 3D printing.

Also check out www.buildyourcnc.com for some ideas on homebuilt CNC routers.

If I had a Bridgeport, I'd never leave the garage. I'm already considering an upgrade!

Merry Christmas!
