Creating plotter-path possible?

[Daniel]

Hi – I like your code, very fascinating. I'm would like to build a simle plotter run by an ESP32 that receives it's drawing path from an SVG calculated by the browser. Since I'm not familiar with all the options you have in your imagetracerjs, could you recommend options so that I would get something as can be seen in the picture below? Thank you very much, Dani

For this project, I was inspired by https://www.brachiograph.art/.

Hi,

Yes, it's possible. As I understand, the ESP32 plotter uses G-code . The simplest solution is translating SVG draw commands directly to G-code commands. I found this https://github.com/em/gcanvas which can convert canvas draw commands. It should be very easy to adapt to ImageTracer, since ImageTracer uses only SVG paths and only M, L, Q and Z commands.

This might not be optimal for a BrachioGraph-like arm-writer, but it's a good start.
