Noisy Star is a model for testing Core One's noise at high speeds, but it may also be used for testing any other printer, especially CoreXY ones.

Star and circle patterns have been chosen to highlight various X and Y movement combinations during printing.

The attached G-code is sliced for PLA at 350 mm/s (200 mm/s for the first layer) with a 0.4 mm CHT (high flow) nozzle. This speed is the default limit for Core One (at the time I made this). Although Core One can print much faster, most users will probably not override the printer's default speed limits. So, I believe it should be representative.

When testing noise, make sure to turn off silent mode, as it limits printing and movement speeds and reduces printer noise.
