Musical Notes from Longmill

I have need using the long mill for some time and love it - yesterday I was creating a sign and measured the board incorrectly so there was a few seconds of the router cutting air. without the noise of the wood begin cut I noticed that the mill is generating a series of musical notes. is that normal? I couldn’t tell if it was the USG software or the control box. you can see and hear this here. - YouTube

Completely normal. It’s most noticeable when the X and Y are running at the same time as in cutting curves.

good to know! thanks.

@sawdustandwoodchips Perfectly normal, but I think mine has better pitch. :grinning:

Mine does the same, but I think it’s crying for dust collection… :crazy_face:
