Hey CNC Woodworkers! Corbin Dunn here and I'm discussing my Automatic Tool Changer, or ATC for my Avid CNC machine. I'll talk about some spindle options and what I got. Then I'll talk about the air compressor setup, which is required for tool changes. Next I'll cover my pneumatic setup and go over the diagram on how I did it. Finally I'll discuss what wires go where in the Avid Control Box. Chapters are located down below if you want to skip to a particular area.

Overall, I'm discussing the HITECO QD-1F ATC Spindle, and the CNC Depot S30C -- or the basic S30, but most people use the S30C for woodworking.

Update Nov 2023: CNC Depot has a lot more ATC spindle options; check out their site: https://www.cncdepot.net

I also have word that their spindles can have Case Pressurization on a relay with 30 psi, which is great!
