Machine Control Software
Commands can be sent with a simple serial terminal. The terminal should be set to N-8-1 115200 baud. Each line should be terminated with a carriage return. Any serial terminal can be used. If you don't have one, the easiest to use is the one that comes with the Arduino IDE.
Select the port that was created when you plugged in the controller via USB. Now select the magnifying glass icon on the upper right of the Arduino IDE screen to open the serial monitor window. Adjust the setting per the image below.
