Quick test of recording from the mill on the $40 amazon USB microscope/endoscope/whatever camera.
Endmill is 250 μm diameter for scale, overall camera FOV a couple of mm. The QFN lands around the perimeter are 500 μm pitch.
Vibration degrades the image quite a bit when the motor is running due to the rather unstable mount I have right now. You can see in the last few seconds when I turn the spindle off, the image quality improves a lot.
Audio is not great, but with a mill spindle and a vacuum cleaner plus the usual lab background noise, I'm surprised I was able to clean it up in post to sound this good. If I move the mic a bit closer to my mouth and speak loudly, I should be able to get intelligible narration out of this for livestreaming.

so I guess the next question is, what's the best option for a poseable arm that can hold a pencil sized/shaped camera at a precise position above a flat surface without shaking around too much when the table vibrates?
I don't even know where to begin looking for such a thing. Drop indicator holder plus some shims maybe?

Maybe it's easier to install a mount on/from the ceiling?
That way you should be able to mitigate all vibrations from the mill.
Also the vibrations that are transferred through the ground/walls will probably be negligible.
