Jetpens is truly a treasure of a website. I've gotten interested in plotter art in the last year and there's a whole lot to learn about how pens work and perform. Jetpens is the essential source for a lot of that information. Some good articles they've written:
Yeah I stumbled upon them years ago just looking to get a nice drafting pencil. Then I got sucked into all sorts of pens, watercolors, and wooden pencils. Maybe I’ll try out some fancy paper next (I’ll take recommendations), but I never figured I could get so nerded out in writing utensils… their marketing is on point…. It’s the write ups like this that do it.
At first I thought it was just a typo, but there indeed something called "Plotter Art" (not to be confused with "Blotter Art", which I just confused it for).
Look at #plottertwitter on Twitter for inspiration.
The AxiDraw V3 is a good small plotter for experimentation. It will support any pen with a vaguely normal shape. The biggest limitation of most plotters is they don't control pen pressure; it's fine for normal pens but won't work with a calligraphy pen that gives variable width strokes.
