So I am totaly new to 3d Printing and my first printer, a Prusa I3 MK3 is now on my way .
I have seen that a upgrate can be made with a raspberry PI Zero W connected to a header on the EINSY board.
But i have also seen that this is not the best option with a webcam : https://github.com/guysoft/OctoPi/issues/318
So most likely I will use a Raspberry Pi 3 for my Octoprint.
But my question is there a advantage to connect the Raspberry Pi to the header on the EINSY board instead of the USB?
Thanks in advance for answering!
