Back currently not good so I have spent a couple of days downloading and playing with as many demos as I can find. I have come to realise that I will probably not find one size fits all. I have tried cambam, cut2d, artcam express, sheetcam and freemill. Freemill seems to be quite good for 2.5d using stl files. So a combination of that for free and cut2d may do what i want for now.

Unfortunately I have a problem with freemill. When I post the code I get the error message -'Fail to write to external file'. I have tried to change permissions on the files but seems to have no affect. Any thoughts?
