@foster.dylan brings up a good point, but I gotta say 62 Rc is on the high end for most HSM routines to shine that dramatically. The variable helix endmill is doing a lot of the heavy lifting there, not just the path. My guess is the tool you were using before had a standard geometry that couldn't handle the heat, and the HSM path plus the new tool just changed the whole game. Glad it worked out, that's a massive jump.

I heard a buddy say canon plugs are basically designed to hide faults like that.

The guy crying about a screen his kid dropped doesn't sound like a defect, just a bad situation. Seems like you were right to bend the rules, but most people with actual defects don't come in screaming.

Nah, fine-tuning is a waste - better prompting and RAG beats it every time for most teams.

Same pattern as people who quit shows after two episodes now.
