Stepper Motor Noise

Continuing the discussion from My startup experience:

It may be worth putting a foam mat beneath the machine. Depending on the table the machine is on, we’ve found that a foam sheet can make a huge difference- some tables act like a drum. The EVA mats used in kids play areas work well.

If you think this noise is something more fundamental, feel free to send us a video. Most cameras have an automatic gain control that can make it difficult to tell how loud something is, so be sure to film some time with the machine alone and some time with someone talking and the machine running at the same time.
