Since then I built out a tool changer system with 7 ISO20 tool pockets on the table. The system runs on Carbide Motion and uses proximity sensors to detect when the spindle arrives at the tool pocket. If anyone’s interested I shot a video of it running.

Jesus buddy allow me to improve your hearing, get a pack of eva foam floor tiles, cut them down to 18" to fit that ultra quiet compressor, get an 18" peice of upholstry foam from walmart, stack it 1 eva tile ontop then upholstry foam then the rest of the eva on the bottom
Get some 3mm or thicker rubber and put it underneath your machine and the table. The resonating frequencies youre experiencing i went through for months without realising how much of an improvement this made. You can now whisper over my machine and compressor
Also that’s sick how much money are you into that spindle and iso20 collets for?
The sound in the video is pretty misleading. Everything is below 70db but the auto gain of the camera brings it all up to fill the audio meter. The spindle is extremely quiet, but in the video it’s roaring. If I had my dust collection running, you wouldn’t hear any of it. I’m sure I could get rid of the resonance though if I added more foam.
I paid about $1500 (It’s $1300 now) for the spindle and $23 for each iso20 holder.
The HDM would be a sweet machine for this. The holders might eat into the machining area a bit if you had them along the Y axis like I did. If the spindle could reach over the front of the table you could have them spaced across the front in the X.
Well this is an amazing bit of work - I had so many questions and they are all answered in your github. Hats off to you! Gives mere mortals like me hope for one-day having an ATC.
