This is Corbin Dunn's customized Mach 4 Settings for an Avid CNC.
I have releases for the screen set and code so other people can use it. The main addition is Automatic Tool Changer (ATC) support for Mach 4.
Installation and directions are currently located here: [https://www.corbinstreehouse.com/blog/avid-cnc-atc-automatic-tool-changer-with-mach-4/]
