The Lowdown
The author shares their recent foray into generative (procedural) art using an unconventional setup. The post serves as a living document of their learning process, highlighting how accessible and enjoyable this niche can be with the right approach.
- Hardware Transformation: An old Ender 3 3D printer, previously gathering dust, is repurposed into a plotter by attaching a fineliner pen to the print head using neodymium magnets. This cheap modification (the printer can be bought second-hand for ~€60) eliminates the need for specialized plotter hardware.
- Software Stack: Inkscape is central to the workflow, utilized for generating gcode from vector paths via the Gccodetools extension. The author also leverages Inkscape's stroke-based fonts (like Hershey fonts) for better plotting results compared to outline-based fonts.
- Scripting for Generative Art: The powerful and well-documented 'Simple Inkscape Scripting' extension (Python-based) is used to create complex generative patterns. This extension's API, similar to p5.js but based on SVG paradigms, integrates seamlessly with libraries like Pillow and NumPy.
- Creative Example: A Python script is provided to generate
