This is the first I’ve messed with this kind of thing (got a little AI help at first). I went into this trying to do something like a spirograph. I’m just barely scratching the surface. I have it making the SVG file which I can convert to gcode. It’s not quite practical for drawing with that many colors but it conceptually works. All of that is passing different parameters to the same function. Small tweaks can make big differences. I’ll have to mess with noise for more organic/random drawings. This is a bit monotonous.
I did get my plotter mounted to the wall and power run through the wall to a supply mounted in my basement. So, it’s back running again. Need to play with LED mounting. I have an idea in my head about making some printed parts to mount LED channel to the extrusion so it’s independent of the frame. I also have to figure out how I’m mounting the paper roll to the wall. I think I’m going to mount it directly on the wall so that too is independent of the frame. I’m not sure what I stand to gain by putting a motor on that.
