I don't think I've ever shown off my "mostly home-brew" ATC (automatic tool changer) on my CNC. Here's the process in action.
Yeah, it looks easy. It was anything but. Lol.
This tool changer literally saves hours and hours of fussy tool changes, touch offs (measuring the next tool loaded), and idle time (waiting for the operator wake up and change the bit, lol). It also helps eliminate operator errors (wrong bit loaded, forgetting to touch-off, or otherwise mangling the process).
The software was purchased from https://cnc4xr7.com/, and then custom modified it to work with my "unique" requirements. Sam (the owner) was amazing and responsive for the changes I needed.
