Hi,
For a post that I have written before, I am looking for a Rasperry Pi 4, but there are serious stock problems… I have seen that there are similar boards, but the doubt is. Which of these plates can Klipper go on? (and that they have USB 3)
Thank you
USB 3 is completely irrelevant for a printer running Klipper. Even USB 2 is significantly faster than necessary. Any reasonably modern SBC running Linux is a potential candidate to run Klipper, but the Pi is easier because of better software support and prebuilt images like Fluiddpi and MainsailOS.
I’m using a pi zero version 2 for more then six month at the same time with a pi 4. No differences in print speed or quality. The only issue that I had was with camera, pi zero don’t provide enough power over usb but with a self powered usb hub every thing works perfectly.
