Strange sounds or music

I finally got my 12x30 Longmill assembled and hooked up. Only one of the two GRBL post processors works and it works fine. Over 5000 lines of code with no stoppages. However the sound/music from my Longmill is bizarre. It sounds like R2D2 from star wars talking to another R2D2! It’s actually quite amusing but is this normal?

The stepper motors can definitely sound like a movie from the 70’s or 80’s that way.

I haven’t had the chance to use mine that much yet, but it made much more sounds than my ender 3 due to the Nema 23 motors.
