Today we are introducing a major refresh of the smallest member of the AxiDraw family of pen plotters: the new AxiDraw MiniKit 2. The AxiDraw MiniKit 2 is our special compact DIY-kit version of the AxiDraw lineup.
Versus the original AxiDraw MiniKit, the MiniKit 2 has been redesigned for easier assembly, better precision, and higher performance. The key change is that the long linear rail that forms the base of the machine — a custom aluminum extrusion in the original — has been replaced with a solid bar of 6061-T6 aluminum, machined in the same precision process as our top-of-the-line AxiDraw SE/A3, and then anodized to a satin-silver finish. This change simplifies a number of the assembly steps, but more importantly has a cleaner overall look and tighter manufacturing tolerances for improved precision.
In addition to be being “Mini”, the MiniKit 2 is also still a kit.
Unlike other models of the AxiDraw family like AxiDraw V3 and AxiDraw SE/A3 (which come assembled, tested, and ready to use), the AxiDraw MiniKit 2 is a machine that you assemble yourself.
We’ve taken great care in designing a kit that is rewarding to build, own, and use.
The new version is also heavier than the old one, which helps it to stay stable on your desk at higher speeds and gives it a small boost in effective speed, in addition to the upgrades in precision. Small but sturdy, The MiniKit 2 is built with machined parts, just one custom aluminum extrusion now, attention to detail, and care.
Like the AxiDraw V3/A3, the AxiDraw SE/A3 has an XY travel suitable for use paper up to 11×17″/A3 size. However, in place of the central extrusion that makes up the body of that machine, the AxiDraw SE/A3 has a central beam that is CNC machined from a solid billet of 6061-T6 aluminum, and then anodized to a sleek black finish.
This heavy, rigid structure — it’s a solid block of metal! — provides dramatically better straightness and stiffness, even compared to the already-stiff AxiDraw V3/A3. This design adds mass exactly where you want it: to the non-moving base that forms the X-axis of the machine. In order to keep the weight light where it matters, the moving Y-axis of the AxiDraw SE/A3 uses the same stiff and light custom aluminum extrusion that we use on the AxiDraw V3/A3.
We made a video showing off the SE/A3, and how it’s made:
Last year while attending FIRST robotics competitions with the Firebots, I had the privilege of serving as a judge at both the Central Valley Regional and the Sacramento Regional. Judging gives an opportunity to get to know the folks involved in the competition, whether they’re students, mentors, or other volunteers like you. I’ve judged and volunteered at a few events now, and one of the great things to see is the way that the community builds and nurtures itself.
One of the students I met in past years, Callie, had graduated from her team, but keeps coming back as a volunteer. Callie was refereeing at both events, and shines brightly as a role model. Literally. She built an LED tiara and programmed it to light in the event colors of red, white, and blue.
She’s a student at UC Davis, and is a truly wonderful role model for the high school students at the events. While you don’t necessarily need an LED tiara to shine as a role model, Adafruit does have a tutorial so that you can make one, too.
In unusual uses for our drawing machines, AxiDraw is playing the role of the master of ceremony in Joël Maillard’s play “Last sheet (after the big lack)”, a production about the robotic future being put on by Theater Marie in Switzerland.
Our friend Arjan van der Meij made this charming musical instrument from a signal generator, a servo motor, an Arduino and a processing program. He wrote an instructable for it so you can build one, too.
He also wrote about his experience with the project in Dutch on makered.nl. Projects like this one, that started with a question (“Why don’t you build a machine to do it?”) are great for learning new skills. I often get asked what things someone should get for learning electronics, and my answer is usually that the first thing you need is a project that you want to make so that you’ll have motivation to research what you’ll need.
Arjan wanted to learn tinkercad, and used this project toward that goal by modeling the knob adapter he’d need for connecting his servo to his signal generator knob. Even if you don’t want to make a musical instrument from a signal generator, this project may provide inspiration for trying out new techniques.
The second annual Robot Art contest Is in its final lap:
The Robot Art 2017 competition will be running between now and May 15th when more than $100,000 in awards will be given to the top painting robots. Winners will be determined based on a combination of public voting, professional judges consisting of working artists, critics, and technologists, and by how well the team met the spirit of the competition – that is to create something beautiful using a physical brush and robotics.
We are pleased to introduce the AxiDraw V3, a new generation of our flagship writing and drawing machine.
This new AxiDraw has been redesigned from the ground up for high performance. It features smooth rolling wheels on custom aluminum extrusions, specially designed for high stiffness and light weight. Its sturdy, rigid construction gives it finer quality output and in most applications allows it to operate at up to twice the speed of the previous AxiDraw, which it replaces.
As with the previous version, AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the body of the machine, making it possible to draw on objects bigger than the machine itself.
AxiDraw V3 is available to order today, and begins shipping next week. See it in action and learn more on the product page.

The AxiDraw is a fantastic machine for making art — along with all those other things that you might use a pen-wielding robot for: Making “hand written” invitations, signing forms, or making neater whiteboard art than one might otherwise be able to.

A few years ago I used your bristlebot design for one of my kid’s classes as a project and it was such a success I’ve done it for each kid (I have 4).
We also made made “pontoon” versions of your bristlebots with 2 toothbrush ends underneath a cardboard oval so it looked like a beetle and gave the kids more decorating space.
Well, now I needed a new project and I came up with the easiest, cheapest Scribblebot I’ve come across, using mostly your bristlebot construction.
The big discovery is that a Dixie cup plus mini markers keeps the whole thing so lightweight. Then put your foam taped pager motor and battery combo on top. It was also way cuter with some antennae and googley eyes. Thank you again for your great bristlebot – it’s made me the most popular mom in each of my kids’ classes.
The bots shown were made by her daughter Kate who also demonstrates them in the video clips. Thank you Kate & Jessica!
