Gary,

Cut 3D works very well. The tutorials do a good job of explaining the software and the tool paths are fine. It is not as advanced as a package like Visual Mill though. You can't select different machining strategies for different areas of your part. It does a good job with models made in MOI. Simply save your model as a .stl file and import it into Cut3D. Make a few choices about your material and how you want to machine it (similar to V-Carve) and within a minute or so you'll have a set of roughing and finishing tool paths. You might want to give the demo a try and also check out FreeMill as Burr suggests. It doesn't have as many bells and whistles as Cut 3D but it works just fine.

Thanks Burr. I learned about FreeMill after I bought Cut 3D. I tried it a few months ago and it works as advertised.
