r/PlotterCode

Made a little tool for plotter friendly line art. You basically upload a 3D object and than define how it should be sliced. Think contour lines on maps, but with more basic 3D models. You can best try it out with one of the demo models and than just randomize the parameters. There's also a morph feature which can create some nice results when not overdone. The tool currently exports to SVG and UNNA TEK specific g-code.

Hope it's useful to some of you. I'm now going back to pushing that randomizer!

>Hey everyone! I’ve been working hard on Plotter-Studio, an open‑source generative art studio for pen plotters (Cameo 5).

My last post was for v3.2 — and I’m excited to share how much it’s grown.

What’s new in v5.5:

🧵 Needles (Oriented Dashes) — short dashes that follow image gradients. Great for structural, flowing textures.

🔗 Continuous Line (TSP) — single unbroken path, the pen never lifts. Uses a greedy nearest‑neighbour TSP approximation.

🌊 Perlin Noise Wobble — applies coherent noise displacement to any engine. Gives clean computer lines a hand‑drawn, organic feel.

🎨 CMYK Layer Export — splits any colour image into C, M, Y, K channels and exports 4 SVGs for multi‑pen colour plotting.

🗺️ Fast Marching (Topographic) — upgraded with manual seed placement, contour smoothing, and “Skip transparent” for PNGs with alpha.

🛠️ Full vpype pipeline — linemerge, linesort (with Two‑Opt), reloop, and linesimplify. All available as toggles.

🖊️ Pen Passes — duplicate dark paths up to 4 times for multi‑pass ballpoint ink density.

Stack: Python, Streamlit, FastAPI, scikit‑image, skfmm, Plotly, vpype.

PENDER Studios is a custom suite of software I designed to convert my Ender 3 V2 3D printer into a pen plotter.

The first release of software is available with the following tools

Harmonograph creator
Laser Wall
.Nc prep
Gcode editor

More tools will be available soon.
