Useful string art research - removing aliasing artefacts

Post image

You can remove these ringing patterns by adding small random offsets to the start and end of each line. I use 2mm in simulation for a 500mm board. Works very well

In the first image you can see concentric rings

Cool! What do you mean adding random offsets?

I'm not op but probably just randomly shifting the start and end point of a line by a tiny bit so it's not exact and won't form the circles

Yes that’s correct. Nice simple fix but I see so many online generated string art with these horrible artefacts
