Heard a guy at the shop say you should never run a program without a dry run first...
He was training a new guy and said it's a hard rule, but I've run thousands of parts on our old VF-2 without one after the first prove-out. I just watch the first few cuts like a hawk and keep my hand on the feed hold. Am I the only one who thinks a full dry run for every single job is overkill?

Man, I get it. On our older Haas, I only do a full dry run for a brand new program or after a major edit. For repeat jobs, I just home the machine, set my Z above the part, and run it slow with the door open to watch the first tool path. That visual check has saved me from a bad offset entry more than once. What's your go-to method for a quick safety check?

Totally agree with @sullivan.kevin, that visual check is key! I do the same thing, run it slow with the door open to watch the first few moves. Saved my butt from a rapid plunge more times than I can count.

Absolutely! I do the same thing, just run it slow with my hand on the feed hold to watch that first approach.
