Re: Cartesio – Low-cost Cartesian plotter robot
#2I wonder if we might see a resurgence of these plotters ala 3d printers.
A tronxy x1 is $85 right now for a full small form factor 3d printer.

#3I don't understand the decision not to use CoreXY. I have a very very similar plotter that also cost me next to nothing using essentially the same BoM as this. It's directly descended from this one [0]. It can absolutely fly, I've spent some time tweaking it but I can reliably and accurately drive it at something like 20cm/s. That's largely a factor of the low inertia of the CoreXY design, which keeps both the main steppers stationary during operation.
Anyway, plotters are dope and to anyone thinking of building one of these, I highly recommend a CoreXY based design.

#4Is there a practical use for this? I’m thinking if my 3d printer does I could repurpose it for this.

I've spent the last several years working with this scale of robot at my start-up. The practical use is mobile phone, tablet, and general touchscreen testing. In some products, such as automotive head unit displays or any medical device with a touchscreen, there are legal and company policy rules requiring that functional testing of a device must match human actions as closely as possible. Which means you can't only test the device through USB or some other back-end developer interface. In other cases, performance/latency testing teams want to test a touchscreen device as a black box, meaning with no extra instrumentation running on the device-under-test, to get good real world performance data. In all these cases that means a capacitive tablet stylus, instead of a pen, is attached to the end of a robot like Cartesio.

#6Plotters are addictive and lovely - look for #plottertwitter on twitter.
I've always loved this spray painting printer (poor quality video, unfortunately):

The people that made AxiDraw also helped put together a kid's kickstarter plotter "Sylvia's Watercolor Bot" which is fun. They also have a plotter that draws on eggs...
I don't have an AxiDraw, but I'd be willing to bet the differentiator from homebuilt is the rigidity of the platform and being able to get very consistent results. (Personally, I'm a fan of 80s pen plotters from HP and Rolond.)

Not sure if this is a dumb question, but what is CoreXY?

Huh, that's really interesting to learn. I'll file it in my big file of "Never thought about it, but makes sense"
(sorry, nothing otherwise constructive in this comment)

#10FYI, if you already have a 3D printer, you can totally use it as a 2D plotter (if that's not obvious).
And you can totally use a fountain pen if you feel like it.
