CNC Build Ep 5: How to Setup an Automatic Tool Changer (ATC) on an Avid CNC – S30C or HITECO spindle



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.

* I used 3/4″ tubing, but 1/2″ might work fine too.
* I actually bought two kits to run piping all over my shop; it was cheaper to buy a second kit.

I have not tested these things for the S30C, so use them at your own risk! I assume the S30C kit package uses a 24V DC power supply and 24V solenoids. If it doesn’t, you will need to source something else. So, before you buy anything, see what your CNC Depot package has.

I got most stuff from Automation Direct, but some things weren’t available from there and I got them from Amazon (warning: these are affiliate links for Amazon).
