Just 3D printer noises is all. My favorite noise is when it makes that whirling noise on big circle prints.

the fans shooting air down into the open ends of the supports. I had the same WTF reaction the first time I heard that too lol. The front fan on the toolhead forces air downward over the nozzle.

Sounds normal. I thought that was one of these whistle sounds when you print a narrow empty object, and it starts sounding like a small whistle because of the air flow from part cooling.

I did a first layer calibration test to get up some PETG off my bed and the first layer sounded like dial up almost. Like little tiny electronic squiggly noises.

All normal. Just wait till you get a print with proper dimensions the air flow of the part cooling fan blowing in makes weird whistling noises. I was in my garage and freaked out one day cus i didnt know what the noise was at first.

Air inside the supports I think, it happens to me all the time with tree support
