I've been trying to get this style of plotter image to work since before 2012: representing brightness with isolines of a function with higher gradients where the image should be darker so the lines are closer

After getting something close but not very good a couple of months ago in the last two days I saw a post on Reddit with a new technique to try (fast marching method) and yesterday I got a process working in Python. Over 13 years and it finally took a day

Hallo #PenPlotter community. I'm aiming to scratch together, out of junk & spares if necessary, an affordable A3 or larger XY pen plotter, that I can feed jobs to from my imagination.

Not scared of electronics or code, just don't want to reinvent too many wheels where avoidable.

While I read all I can about this format of drawing robot, any recommendations to get started would be very welcome.
