Just pulled the trigger today and bought cambam. I have been impressed on a daily basis seeing the capabilities of the software. Way cool. I hope you continue to expand your operation!
What I would like to see in the future is more support for 3D models, possibly STEP or IGES. I usually work in 3D and it would be helpful to use a solid model that isn't a bunch of triangles. :-)
Keep up the good work!
