Home Made Pen Plotter

As someone who started using computers in the last century, I find the current resurgence of pen plotters somewhat nostalgic. The difference, of course, is that this century it is easier to make your own, which is what [Miguel Sanchez] is doing.

Inspired by the Axidraw, he is making his own pen plotter. He’s made great progress so far, creating a design that looks quite simple to build. His design is driven by an Arduino Uno with a stepper shield, a couple of NEMA 17 stepper motors and a servo to raise and lower the pen. Throw in a few rods, a belt or two and a number of 3D printed parts, and you’ve got a decent looking pen plotter.

He originally started with laser cut components, but shifted over to 3D printing as the design evolved. It’s not as fancy as the HP pen plotter I used to print out rude words in giant letters with in my youth (a HP7475, I think), but it is a neat build. Check it in action in the video below.
