This exam time you can make this cnc homework writing machine.This CNC is controlled by arduino nano micro controller.For the X and Y axes we will use one stepper motors and for the Z axis we will use a small servo motor that moves the pen up and down.
The machine uses a gantry to move the writing tip along the X and Y axes. The flexible-nib calligraphy pen is mounted on a sprocket which rotates the tip onto the writing surface, taking care of the third axis.
You can use the machine to do pretty much whatever you can dream up from drawing fancy artwork to extensive calligraphy on letters.
