Thanks guys. I did indeed use shielded wire and ground according to the video. Perhaps I am overthinking it. I just didn't like the fact that the wires are so close to the toroid.

I finally finished pulling all the wires for ATC. I guess I didn't expect them to take up as much space as they did :cry:

My concern is that when the door to the enclosure is closed, it pushes the wires closer to the toroidal transformer than I expected.

Do you think it is worth moving the toroid ...

Makes sense.

Thanks. Great explanation! In this case, N/O will work great!

I am ordering a couple proximity sensors. One that counts tool position on an ATC. The other senses clamped/unclamped status for the drawbar used in conjunction with the ATC.

Technically, N/C sensors provide better indications if a wire breaks etc. While I can source one that is N/C (it is also PNP ...

Thanks Greg. I am using a similar pulse generator and Nema 23 stepper. I am wiring and bench testing now and looking forward to getting finished up. Thanks again for your thoughts. If you have any other images you have, I would love to see them.

Yes, there are lots of helpful folks on this forum ...

Greg,
Thanks for your input. Very nice build! Just wondering if you found getting the ATC perfectly aligned with the spindle difficult or fidley. It seems like these TTS tool holders have to be aligned perfectly concentric with the spindle. This has been my greatest concern all along.

One last ...

Wow... What a cool idea! Just curious, is that tool changer the one designed by David Loomis? Are you using TTS tool holders? Is your air blast inside the carousel or external to it?

Thanks... Richard

Thanks for your insight, Marc. My milling machine is an RF clone benchtop mill with no ability to blow air through the spindle.

This Automatic Tool Changer was specifically designed for the TTS tool holder system that I currently use. It has a cover to keep chips away from the tool holders. It ...

Thanks Uwe. Standing by.
