Plots

I’m plotting again after an August hiatus. The new Gondola Plotter is super quiet, so nice! I’ve made a few refinements to the software stack of course… The usual.

I found a bunch of really cool engravings in some very old books I found in the abandoned house. These books are worthy of some discussion on their own much like the old vinyls, but this isn’t the time.

I got ChatGPT to make me a few SVG handling tools that are really incredibly well done and will help me shed some of the apps I was using. With SVGs there really is not a single app that does all the things, so I drag a collection around just to use 1 or 2 of their function. AI is helping me write scripts to explore algorithms and replace more trivial functionality from apps.

Case in point: this super cool recursive inset fill algorithm to turn fills into something a plotter can do.

I’ve been wanting to write this one for a while, but I knew it’d take me a good few days to nail it. That got turned into 30 minutes with AI. Jaw dropping. I love the effect as it echoes a lot of bored fillings of shapes I’d do as a kid getting bored in class. The cookstove above is filled with it, but it’s far too dense at this size and so it really looks like a actual fill rather than a particular effect.

A lot of my tooling these days is Python which has good libraries for handling SVGs. I used to dislike Python for their dumb purist move from 2.7 to 3 which wasted everyone’s time, and because they had managed to reimplement library hell. But I have to say venv is a successful redress to the later.

SketchyBot 1.0

I finally built a standard sized one. I ran into a few unexpected challenges given how smooth the small one went.

It really isn’t the most accurate machine, the belts inside aren’t timed, but it does pretty ok with some rendering algorithm and is fun.

Winter Warmth & Shitty Servos

I launched another big plot, it was a 7 day one, I swapped the servo motor for the occasion to reset the pen up/down cycles it would have, but that was a bad idea. I think I’ve learned it’s better to stick with a lucky servo that keeps performing. And so on day 5, the new servo failed. So I stopped things early, the plot still looks pretty good, you might recognize it from this post.

Bellow is the unfortunate artifact of a pen that doesn’t go off the paper. Another interesting thing I’ve learned from these large deployments, is that the slight misalignment I keep having from one plot to the next, but not enough to be a real bother, I think is due to the paper or the belts loosening over the days.

An so I bought a couple of very premium servos, it’s time to get hardware in line with the ambition. I’m hoping they’ll make a difference. They better.
