Theres a lot of SomethingCAM packages about, its not easy not to get confused ;-)

CamBAM also offers a free trial and works very well for 2D, cutting things out of a flat plane.

Personally found Meshcam easier for 3D cutting and harder for 2D cutting, then the Vectric 2D module seems popular here....

Try the free trials of things and see which you feel most comfortable with.

It`s the one that gets the object off the screen and into your hand that wins :-)
