With something like this, how do you handle the period of time while copying? I mean you can’t really leave it running as it wouldn’t be in a consistent state. A “under maintenance” page instead? Copy to a fresh folder and when done tell the webserver to serve the new location?

That is not the case for every country though. In France and Germany for example almost 3/4 of google requests are via IPv6.

And the firmware inside that rp2040 is stored on plain old flash memory. So while the data may still be on the memory chip, the controller chip dies at just the same pace than every other usb drive - and then you can’t access it.

You do not want Octoprint on a machine that is busy. Otherwise you have load spikes that cause Octoprint to not be able to send the move-commands (gcode) as fast as the printer executes the movements. This problem is pronounced with faster printers and slicers that break up arcs into small straight lines (which is practically all slicers). Otherwise your printer stutters because it has to take small breaks to wait for the next command from octoprint.
