I tried searching for answers as to why these machines are reaching out to numerous locations despite not using PrusaConnect. Location lookup returns the expected Czech, as well as location across the US. I recently also set a friend up with with an Elegoo printer and that was expectedly noisy as hell, but I was surprised with Prusa being the 'privacy pick'.

For those curious, here's the logs since about midnight, it seemingly doesn't talk during the day.

Prusa is a 3d printer. It can be to show the date, check the validity of certificates, show in logs, or just tell you when your print will be done.

AFAIK the firmware is open source so ultimately you can look exactly what it does with it. Same as any Linux system, really.
