> Many forum members here say the advantages of _one g-code program per tool_ is that you can change the program for a certain tool easier or re-run a pass easier. They put the name of the tool into the file name, and the pass that it is for.

Yes to this. I used to be in the camp where I wanted to keep all tools in the same program. But because I don’t have an ATC and am not running production on anything, I find it more convenient and flexible to actually program for separate tools. So even though I _can_ program for tool changes, I prefer not to.
