Re: [CAD_CAM_EDM_DRO] Drilling with Vector

Super! That did it, Tim. You've saved me a bunch of time and frustration.
Now a question:

It looks like your solution was generic, rather than Vector-specific. I
hope I'm just missing a Vector function that would have generated that code
without my editing. Was your solution based on Vector, or general knowledge
of G-codes?

Thanks a lot for your help.

Dave
