This homemade PCB Ink plotter is built using Arduino running GRBL CNC firmware, 28BYJ-48 stepper motors, 3D printed parts and other few other hardware. Video is played at 4x speed.

The build is based on the design from Dirk Herrendoerfer (   • Direct ink to PCB CNC-Plotter pt. 3  ) and the firmware is based on https://github.com/ruizivo/GRBL-28byj....
