I spent a lot of time and money looking for CNC software that was right for me. I couldn't find it so I wrote my own.
smart arse ... makes me feel a little less than clever

But who uses AutoCAD these days?
iv pretty much got my work flow squared away now but im pretty sure in the early stages of trying to crack the CAD to CAM issue i would have twisted your arm for a beta of your RCNC and id have learned AutoCad/ProgeCAD and given the thing a go given how simple you make it sound to use and how expensive and complex software can get

if your making molds with it its obvously working well

im gessing that drawing paths for thread milling might be tedious and the lack of a 4th axis would put some off but im kind of hoping somone who is just starting out and isnt after those functions WILL twist your arm and give it a go

nice one robin xxx
fingers crossed and good luck with it :)
