Re: [CAD_CAM_EDM_DRO] CNCpro VS Artisan

Larry,

Are you forgetting that Ah ha also impliments G41 and G42 cutter radius
compensation also? I did not think any of the other controls you mentioned
support this important feature.

Anytime your tools wear some, do you go back and redraw your cutting paths?
With the G41, G42, you can simply set the tool radius to the new width and
re-run your part without going back to the drawing board. I think this is
an important feature that Ah Ha offers, and it works.
