You could have a look at Estlcam, the demo is free, and if you like it, it is only 50 Euros or so to licence it. It has a lot of features and I have just done my first job with it. There are video tutorials on t'Interweb. There are some aspects I don't like - I found it easier to start again from the dxf file if I messed up a toolpath (rather than deleting the toolpath - which seemed impossible) Maybe I will get better at using it, but if I find foibles which need to be sorted, I will address them with the author (Christian Knuell). In my correspondance about licensing, he seems happy to help.

Cheers,

Rob
