Have you ever seen a plotter or CNC (Computer-Numerical Control) machine and thought "wow, I'd like one of those"? Well now you can make your own based around an Arduino or compatible hardware and the notes by Instructables member ardumotive.
They describe a desktop CNC plotter that not only introduces you the theory and control of a CNC device - the results are the neat unit shown in the video below.
Apart from the hardware and Arduino sketches, you are also introduced to converting images into the required instructions in order to have them created by the plotter - a complete package.
If you're looking to develop projects based on an Arduino that use stepper motor, CNC machines on a larger scale, and much more - simplify the process with our Freetronics StepDuino board:
The StepDuino is a complete, self-contained Arduino-compatible board with 2 onboard stepper motor drivers, 2 servo outputs, a 20x4 LCD, a micro SD card slot, and more! It's a fantastic general purpose board for any project that uses stepper motors. You can use it as the brain of your next robotics project!
The StepDuino uses the same processor architecture as the common Arduino Uno, so you can program it right from the Arduino IDE simply by selecting "Arduino Uno" as the board type. Everything simply works out of the box, just as it would with a regular Arduino - but now you can also drive steppers directly and display feedback on the huge LCD.
