Software
Generative-art software, plotting drivers and SVG tooling to drive your machine.
The software side of plotting trips up more beginners than the hardware. The good news: the best tools are free and open source. You need a way to make or import vector art, a way to optimize it, and a way to drive the machine — and free tools cover all three.
Inkscape designs and sends to the plotter, vpype optimizes any SVG so it plots faster and cleaner, and p5.js or Processing let you generate art from code. Our reviews and guides below cover the tools that actually matter and how to use them together.

Free, open-source software that turns photos into plottable line art — sketch, stipple and hatch styles that export clean SVGs for your plotter.
Best for: Converting photos into plottable sketches and stipple art
The free, open-source vector editor that doubles as the native design and machine-control interface for AxiDraw and NextDraw plotters.
Best for: Design and machine control in one free application
The command-line Swiss-army knife for pen plotter SVGs — optimizes, reorders, merges, crops and prepares vector files for cleaner, faster plots.
Best for: Everyone — mandatory step between generative art and plotting
The foundational Processing reference from the language's own creators — the bedrock under a huge amount of plotter art, and the book you keep open while you code.
Best for: Properly learning the language behind plotter art
A lavish, example-packed guide to visual programming for generative art in Processing — one of the best idea wells you can keep next to your plotter.
Best for: Finding generative forms worth plotting
The book that teaches the generative-systems thinking behind great plotter art — flow fields, forces, noise and autonomous agents, all in approachable code.
Best for: Learning to generate art worth plotting
At minimum a vector editor (Inkscape), an optimizer (vpype), and your plotter's controller (AxiDraw plugin or a GRBL sender). All are free.
p5.js for beginners (runs in a browser) and Processing for desktop work — both free, both export SVG for plotting. vpype then optimizes the result.
Not to plot existing SVGs. To make generative art, a little coding helps — but p5.js and Processing are designed for artists, and remixing examples is a legitimate way to start.
