CD-DVD CNC Pen Plotter
I made this small CNC with parts recovered from old CD and DVD players.
It has very small dimensions and is only capable to make drawings with a pen.
I created the Z axis that allows to move the pen with my 3D Printer:
There is a guide, always retrieved from a CD player, to prevent the pen from rotating and getting stuck in its seat when pushed by the servomotor:
To lift the pen the servomotor pushes it upwards:
The 3D model was designed with SolidWorks CAD software:
The whole mechanics comes from CD and DVD players, like the X axis movement screw:
The drawing plan is a sheet of metal obtained from the structure of a CD player:
The X and Y axes are moved by the stepper motors of CD and DVD players:
The electronics is based on an Arduino with GRBL firmware:
To which the two stepper motors and the servomotor are connected:
The frame is also made of sheet metal from CD and DVD player boxes:
