I am a new user just getting started. When I turn on my S1, it moves around the laser. I assume to make sure it is in the correct initial position.

The first thing it does is raise the laser module straight up until it stops and makes a noise like grinding gears. I thought this was normal but I just watched a video where someone started up their S1 and it did not make the grinding sound.

Is what my S1 is doing normal? Did I make a mistake during setup?
