I have a haas super mini mill, and when I change tools I go into the machines control panel and change all of the new settings ( tool length, diameter, flute qnty, and tool type )

Other than the tool length, are the rest of the settings just for reference?

In other words can I just get away with changing the tool length field?

I'm using Fusion 360 to create all of my code, so all of my tool info is being managed on that end of things.

Thanks,

Kent
