Howdy AVID community, With the New ATC and suggestions on how to load large mills? As I load my 3.25” cutting tool T14, the tack in the back extends and tried to measure it, it is much too large for use the tool touch off sensor without hitting stuff on the rack. I usually hit cycle stop and then run → utility → calibration → manually touch tool off work surface. [](https://www.youtube.com/watch?v=WqVBncfCZEk) Best, Max ---

This workflow has been refined on a forthcoming update you should see next week. It will automatically give you the option to do a manual measurement on a large tool diameter ---
