Supporting the machine?

[Robin Hewitt]

Steppers don't rattle unless you full step them, they purr.

The noise is the spindle motor and the tool hitting the workpiece. Only annoying if high frequency.

If it's a mill you should be fine sitting it on fat rubber feet.

If it's a router, your only hope is an accoustic hood :whistling:

So in relation to an acoustic hood, would it be fair to say I only need to consider materials that will deal with the higher frequencies instead of being affective across a broad range of frequencies?

I think 'rattlers' may have been referring to dampers you put on the motors which allegedly reduce resonance?

I think the rest of it is negligible compared to the noise/vibration caused by cutting.
