A guy at the Tacoma trade show told me I was overthinking my toolpath strategy

I was setting up a demo for a tricky 4140 steel part and explaining my multi-step roughing plan to a small crowd. This older guy, named Frank, just shook his head and said, 'Kid, you're making a 2-hour job into a 6-hour job. Sometimes the simple contour path is the right one.' He showed me on his phone a video of a similar job he ran in his shop in Spokane, using a single 1/2 inch carbide endmill and a basic adaptive path, and the finish was perfect. It really stuck with me. Do you guys ever find yourself overcomplicating programs when a simpler approach would work just as well?

Frank from Spokane is right, I spent a whole week programming a fancy trochoidal path for aluminum that a simple climb mill would have done in half the time.

Oh man, Frank sounds like the kind of guy who just gets it done. I've definitely spent an afternoon writing a "smart" program only to realize I re-invented a straight line.

That trochoidal path story hits home. Last year I watched a junior engineer spend three days building a custom dashboard to track server temps. He used three different libraries and wrote about 500 lines of code. The final product displayed a single number that blinked green or red. The built in system monitor did the same thing with one command.
