Getting a tool length compensation issue when making toolpaths

I would agree with those thoughts David, it seems to me to be a one off kinda screwup that I easily could have done by shutting down wrong, turning off the power while still connected, etc. Something stupid one does before they understand how things work (whatever the thing is)! I’m just saying I definitely did not sit there and type that crazy number in there, no way, no how.
