This video is not specific to the MP Select Mini. Here is a short example of how to download, extract, and run Printrun/Pronterface so that you may send G-Code commands to the 3D printer.
Pronterface is a good piece of software to keep in your 3D printing tool kit.
Make sure you use a good USB cable.
