    Interesting. That's why I always use an outdoor antenna if at all possible. Since the printer is at the other end of the house, it may be noisier than I think it is. BUT I do know the power supply is terribly noisy, since I can hear it all the way to my shack if it doesn't have it's ferrites.

    My power supply and printer power cord came with the ferrites. (Ender 3 Pro 3D printer)

    But the RPi in a plastic case radiates a lot when you start connecting things to it.

    Many use a Metal case to make use as a CPU heatsink. The RPi 4 needs a large heatsink. The RPi 3 runs cooler.

    Using WiFi instead of wired Ethernet for the Pi can help a lot.

    The USB cable that connects the printer to the RPi needs a ferrite also.

    Normally when I 3D print, I ignore the radio and my wife. :oops: I pay attention to the smoke alarm. :)

    3D Printing at 250 C can be fun and challenging. Hot is the new cool. :) Can you say "Stuck to the bed" lol

    that could be one difference. Mine is in an Anidees metal case that is grounded. It's got a heatsink in it, and a few extra holes... so it doesn't get too hot. And it's not on the network. It's amazing how small changes can alter things.
