Hot take: I keep seeing guys at my shop in Milwaukee set their tool offsets with the spindle off
They'll jog the tool down, tap the part, and just hit 'measure' while the machine is totally still. It works okay for a rough cut, but try that on a finish pass for a tight tolerance job and you're asking for trouble. I learned the hard way on a batch of 50 aluminum brackets where my finish was off by almost two thousandths. Has anyone else had to fix a part because of a cold spindle offset?

Spindle heat changes everything, learned that after scrapping a run of stainless fittings. Always warm up the machine first.

Watched a guy try to cut some tight-tolerance aluminum parts on a cold Haas once. The first few came out perfect, then the rest slowly went out of spec as everything expanded. He spent more time checking parts than making them. That lesson seems to come from ruining something expensive.

Ever wonder how much warm-up time is actually enough? Like, do you just run the spindle for ten minutes or do you need to cut some air first? I saw a shop try to write a warm-up program that made the machine move through its whole range of motion. Did that help or is it overkill?
