Re: [CAD_CAM_EDM_DRO] CNCpro VS Artisan

No, I didn't forget Ahha supports cutter comp and the others
don't.

Ahha has a lot of features the others don't. But, those
features aren't
as important to me as smooth motion from a look ahead
buffer.

I have hever used cutter comp. I don't cut many parts. I
don't wear out
many cutters. I'm not a production shop. So yes I would
regenerate my
G code file if I needed to change a cutter. If I found a
worn cutter, I would
simply throw it away and buy a new one.

For someone that needs cutter comp, then yes, Ahha is a good
solution. Like
I said, I have two of them and still use them.

later,
Larry E.
