This looks like great fun, but I'd prefer to make something where the output is a little more precise. Does anyone know of a DIY plotter that's a step up quality wise from this one? Or maybe a site or community that lists similar projects?
I bought a kit called the EleksDraw and found it for $140 shipped. It uses G Code and didn't take too long to put together maybe a couple of hours at a slow place.

It's my understanding that higher quality plotters/3d printers/mills' accuracy and precision come from higher quality motors (e.g. stepper motors instead of servos). Will it be possible to someday just put cameras on the plotter which watch the current print and self-correct as needed? That's basically what our eyes do when we write/sculpt/carve. Will cheap motors + cameras + software eventually meet or exceed the qu…
Rigidity is a major factor--if you inspect one you'll notice that high speed and high repeatability machines (e.g. a 6-axis +/- 0.020mm repeatability manipulator) are made from rigid (often high-mass) components with robust joints.
Awesome to see pen plotter stuff posted here with more frequency. This project is pretty amazing in its frugality, kudos to the author. I have another pen plotter and I'd highly recommend pen plotting to anyone who's into generative art or anything similar, it's really fun to write a few lines of code to generate some visuals and then watch the plotter as your design is made into something tangible. I'm working on a…
And if you want a COTS replica with a bit more polish: https://www.line-us.com/

Or you could just laminate that cardboard with some fiberglass and epoxy, on both sides. A roll of 5cm x 3000 cm fiberglass woven cloth is $9 incl shipping on ebay. Buy some two component epoxy at the local hardware store, like 10 fl. oz. for $15. Cut your cardboard and fiberglass to whatever size and shape you like. You're going to make a sandwich: fiberglass, cardboard, fiberglass. Wear disposable gloves. Cover you…
I'm a huge fan of Peter Brown on youtube, I've been wanting to get into using epoxies for various projects, it's just that I live in a small apartment, I'm not sure where to start, and I know I'll need ventilation. I'm biased towards 3D printing simply because I already have my own printer, so it's simply the fastest method for me (not including print time, but epoxies have to cure anyway).
I would actually expect more of a ventilation requirement from your 3D printer! Here is one set of safety recommendations for working with ABS/PLA: https://www.safety.rochester.edu/ih/3Dprinters.html
But if you are really worried, go get a 3M 7502 mask with a 6001 organic vapor cartridge. These are cheap. That's what the manufacturer (West System) MSDS says to use in case of no ventilation.
Skin contact is a bigger concern. 1 in 5 develop dermatitis upon skin contact, and some get more severe allergic reactions. So wear good gloves, blue nitrile ones that fit well with decent thickness, not the cheap latex stuff.

Here's my old faithful Printrbot plotting a dragon curve:

FWIW, every 3D printer is also a pen plotter (just stick a pen to your print head!).
