I wrote about it here, but if you have any questions I’m happy to describe it more. > [@Things I learned setting up an ATC spindle](https://forum.avidcnc.com/t/things-i-learned-setting-up-an-atc-spindle/4421): > > In case it is useful I thought I’d share some of the stuff I learned the hard way instead of reading the directions.
