摘要:The paper describes the design and the implementation of a small, easily operable and flexible 2-axis CNC pen plotter (Computer Numerical Control). It is accomplished from two old and available CD-ROM (Compact Disc Read-Only Memory) drives using their stepper motors and the main hardware structure. The two stepper motors move the pen platform along X and Y axis. The plotter has been tested for printing different images and texts. Thus, the functional and graphical requirements were demonstrated, the conclusion being that this device is efficient and precise, and it can be easily achieved from available components.
