Clever use of some old electronics from u/pheux9558 on Reddit. They fashioned this drawing machine!
I‘m using old CD drives for the X and Y-Axis, an old Floppy Drive for the Z-Axis and a servo motor to move the pen. I wrote the whole software by myself. On the Arduino is a G-Code interpreter to control the movement via coordinates. On the Raspberry runs a Python software to manage the upload of the G-Code per Serial. The GUI is currently in development. On the Arduino Uno is a prototype software of an GPIO extender I wrote, to program, read and write Arduino pins with a Python script. It took me 4 months to do it. Leave your thoughts in the comments
