I finally tuned the plotter a bit to make it perform faster. I was trying to make it move faster by increasing the stepper motor speed, it turns out optimizing the pen up/down action was really where all the slowness was and makes everything appear to run faster. It’s quite spiffy now and I’ve been plotting non-stop this past week.

Someone in Brazil drew this on Mandalagaba years ago and I’ve used it to stress test plotters since :). I wish I could get in touch to show them.

The Four Sisters

I’ve gotten pretty good at producing these.

The best part is always watching them being drawn
