The Octopi Distribution is "Ready to use" and has been specially adapted to the Weedo X40 PRO. You only need to save the image on a MicroSD card, insert it into the Raspberry Pi, connect it and switch it on. After logging in, you can use Octoprint immediately.
The distribution contains buttons to control the printer, as well as a thumbnail plugin specially programmed for the Weeedo X40.
