Re: CAD2lathe software

Dan,

Yes, I was saving as R12 but there are 3 different types of R12 and more stuff to mess with if you dig far enough. I thought a dfx was a dfx until this mess. There is a lot more to this than I am willing to battle with.

I need a lathe cam that will do the job w/o lots of fiddling. Being able to draw tool paths looked easy and the price was right (wrong!)

I have considered hacking with Rhinocam as a code generator and may try that. More likely I will buy VisualTurn eventually but can't afford it now.
