If you have a 3D Printer and you are still moving your gcode to it by SD Card, then this video is for you. I have to admit that I initially setup Octoprint (Octopi) just because I thought it sounded really cool to connect a Raspberry Pi to my 3D Printer.
This video will walk you through the process of installing it and getting the basic setup done.
You are going to need a couple of programs to start:
Win32 Disk Imager: https://sourceforge.net/projects/win32diskimager/
One of the following 2. (AngryIP for the computer, or Fing for a mobile device.)
Angry IP Scanner: angryip.org/download/
Fing: (Mobile) https://www.fing.io/
Now, sit back and watch the video! (Links to the products you will need are at the bottom.)
If you do not already have one:
