In the video, you will also see the insertion of the motor wires into the driver. Very important, the motor wires must be connected while there is no power to the board at all. "At all" means, .01 volts, that when you power off the power supply, the capacitors are insuring that there is still power to the board, and the capacitors take time to release all of their energy. It is recommended to wait at least 3 minutes after powering down the supply before connecting or disconnecting the motor wires from the driver board.

Also in this video, you will see a test of the machine. You will get a glimpse of the software that I use (explained in a later post). I run a g-code program (interpreted by EMC2) to determine if all of the motors are functioning correctly. G-code is a language that tells the CNC what to do. If a very simple language that nobody ever wants to learn. EMC2 is a software application that takes g-code, interprets the code into step and direction signals and sends them to the driver board. Don't worry, I will explain this in much greater detail in a later point, including a tutorial on the g-code language, and cheap CAD/CAM techniques.
