Hi guys for this first message i would just like to talk about my experience.
I discovered 1 month ago Octopi/Octoprint and decided to install it on my old Raspberry Pi (rev. B, 2011).
It was just a nightmare, soooo slow to start, to install plugin, to update, etc.
Finally, I decided to buy a Raspberry Pi 4, and the only think i can tell is WTF! I was soooo stupid to wait so long to acquire a Pi 4!
Everything is so fast so smooth so great!
So please DO NOT INSTALL OCTOPRINT on old version of PI like mine and just follow recommendations!
Guys, you made a great job! thanks for everything!
