Spent 2 years climbing around with the wrong G-code for my Haas

I was always wondering why my parts on the VF-2 had these weird chatter marks in the corners. One day a guy from the next shop over came to borrow a wrench and watched me run a part. He just laughed and pointed out I had my arc feed rate set wrong, like way too fast for the radius I was cutting. That conversation saved me about 200 hours of frustration a year. How do you all dial in your finishing passes on small radius cuts?

Man that's brutal. Two years of chatter marks and one guy with a wrench saves your whole operation.

Sounds like you're buying into the hype a little too much. A worn out part and a simple fix doesn't really scream "saves the whole operation" to me. Most of the time those chatter marks are just cosmetic unless they're actually causing the machine to shake apart. Bet they would have figured it out eventually anyway, maybe just took a little longer. This is just a normal day in maintenance, not some heroic rescue.
