#PenPlotter maintenance today. My HP 7585B stopped responding over RS-232. Diagnostics revealed a problem with the interface card. Luckily I have a spare machine that can donate a new working card!
And it works! Here’s a video of the HP 7585B #PenPlotter plotting a big arc Truchet tile design using three colors (yellow, cyan, and magenta) on 11x15 watercolor. Total time 1h15m.

@paulrickards That's astonishing engineering. Perhaps par for the course for plotters, alas I never got to use one, but the precision needed to return the paper to the exact location multiple times without drift. Brilliant.
Had a draining week, mind was fried... Finally found two hours of flow Sunday evening! Used it to generate lots and lots of small rectangles. Loosely inspired by Aiyu's 'Memory Flow' on fx(hash).
Or is it Voyager's hull plating after a particularly rough patch in the Delta Quadrant?
Take two is a big improvement. I disabled all optimizations, so it draws the lines in a predictable order removing previous discontinuities. #penplotter#CreativeCoding#axidraw#openrndr
@migurski Actually no. It's very interesting why it happens: the paper is initially flat, and the brush height configured to produce super thin lines. As it starts to draw, the humidity bulges the paper up, which makes the brush paint wider lines. I can imagine the paper acts as a very slow wave moving up and down, affecting the stroke weight. Quite special :-)
First time I use this brush/pen. Probably the highest contrast plot so far. I like how lines become thin and thick due to paper bulging when it gets wet with ink #penplotter#MastoArt
