My retired foreman from the old shop called me yesterday and said 'you're not just a button-pusher, you're a problem solver with a machine', which hit different after a month of running the same simple job.
He said it after I told him about fixing a weird chatter issue on our old VF-2 by adjusting the feed and speed by just 5%, and now I'm curious what small tweak other operators have made that saved a big headache.
