I have an Anycubic 13 Mega which I am going to try to run with Octoprint. As it happens, I had a Raspberry Pi unit with built in screen, sitting in a drawer, going spare. So I was part way there.
I removed the existing SD card from the Raspberry Pi and used this to load the Octoprint image as per the instructions. It took me a while to work out that I needed to download Notepad++ to allow me to modify the network settings.
I have Raspberry Pi 3 Mobel B V1.2
This was originally used with a Photocentric resin 3D printer, which I had to get rid of, due to a major allergic reaction to the resins. I kept hold of the controller as it was an optional extra which I thought I might want to 'play' with in the future.
So here I am.
Do I need to plug a keyboard and mouse in?
