lmao - sorry, but I've been around long enough to have been alive when personal computers did not exist.

When i started out in business I was setting up token ring networks, where if one connection went down so did the entire network. That was fun !
Even today networking isn't particularly reliable.
For something like a 3d printer, you want the most stable data delivery you can get. Which is always going to be reading a file either stored on a printers internal memory, or off a storage device directly attached to the printer.

So why won't octopi connect via the usb port ?
