Re: [CAD_CAM_EDM_DRO] Re: Question about angular and linear feedrates

Rab,

EXACTLY what I wanted to know, and why I had asked the question in the first
place. Of course it isn't a perfect solution, but it does make the program
useable without further processing. Of course, I got grilled after
suggesting such a blasphemous thing, ;-).

Thanks for all of the help, everything is working "perfectly" again.

Dan.
