Old timer at a shop in Denver told me to stop trusting the machine defaults
I was running a Haas VF-2 over in Denver back in March and this older guy walks up, been doing CNC since the 80s. He watched me set up a job and stop to check the default tool offset. He said "son, every one of those factory presets is a lie" and walked off. I ignored him for about a week until I crashed a $400 endmill because the default feed rate was way too high for the material. Now I manually recalculate every single speed and feed before I hit start, even if it adds 15 minutes to setup. Has anyone else found hidden wrong defaults in their machine's presets?
