Precision pen plotter: Compact DIY kit edition
The AxiDraw pen plotters are a family of simple, modern, precise, and versatile machines; capable of writing or drawing on almost any flat surface. They can write with your favorite fountain pens, permanent markers, and other writing implements to handle an endless variety of applications.
The AxiDraw MiniKit 2
The AxiDraw MiniKit 2 is a special compact addition to the AxiDraw lineup. Designed for lighter-duty applications, It takes up less desk space and less storage space. It's considerably more portable, too.
The AxiDraw MiniKit is also the only DIY kit model of AxiDraw that you get to assemble yourself. (All other AxiDraw models ship fully assembled, tested, and ready to use.)
A Mini Plotter
The AxiDraw MiniKit 2 has a working area of about 6 × 4 inches (150 × 100 mm): Big enough to be useful for a wide range of applications including short notes, postcards, and addressing envelopes.
It's also ideally suited for use as a signature machine, for signing checks, letters, books, or artwork.
The AxiDraw is an extremely versatile machine, designed to serve a wide variety of everyday and specialized drawing and writing needs. You can use it for almost any task that might normally be carried out with a handheld pen.
It allows you to use your computer to produce writing that appears to be handmade, complete with the unmistakable appearance of using a real pen (as opposed to an inkjet or laser printer) to address an envelope or sign one's name. And it does so with precision approaching that of a skilled artist, and — just as importantly — using an arm that never gets tired.
What's new in AxiDraw MiniKit 2?
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 MiniKit — has been replaced with a solid bar of machined aluminum. It's a solid billet of 6061-T6 aluminum, machined in the same precision process as the top-of-the-line AxiDraw SE/A3, and then anodized for toughness and 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. It also adds some mass, helping it to stay stable on your desk at higher speeds.
Who uses AxiDraw?
AxiDraw plotters are used by a genuinely diverse range of people, including (to name a few):
- Digital artists, using AxiDraw to plot their artwork
- Celebrities, politicians, and elected officials, using AxiDraw as a signature machine
- University officials and other educators, to sign diplomas and certificates
- Educators, introducing students to digital design and fabrication
- Real estate and insurance agents, who would very much like you to open their "handwritten" envelopes
- Online retailers, including a personalized thank you note with your order
- Hotels that would like to leave a personalized welcome note for guests
- Makerspaces and hackerspaces, providing a versatile low-cost fabrication tool
- Tinkerers, extending AxiDraw beyond writing implements (etching tools, lasers, LEDs for light painting, vacuum pick-up tools, etc.)
- Pen and ink manufacturers, using AxiDraw to test their pens and inks
- Smartphone and tablet hardware makers, using a stylus to test their hardware
- Mobile device software authors, using a stylus to test their software
- People without use of their hands, who would like to send "handwritten" letters
- Woodworkers, laying out joinery markings directly onto wood
- Research scientists, as a low-cost XY motion platform
- Galleries, for numbering of limited-edition artwork
- Calligraphers, who could use a little wrist relief for certain types of busywork
Handling pens and paper
The AxiDraw comes with a small mounting easel (board with clips) that can hold note cards, envelopes, gift tags and other papers. You can also set the AxiDraw directly on top of drawing surfaces like boxes, notebooks, and larger papers to add graphics in place. Your paper size is not limited to the working area of the machine; the unique design of the AxiDraw features a drawing head that extends beyond the body of the machine which allows for drawing on whatever object is positioned in front of it.
The AxiDraw MiniKit 2 uses the standard AxiDraw pen holder. It fits a wide variety of pens, including Sharpie fine and ultra-fine point markers, most rollerball and fountain pens, small-bodied whiteboard markers, and so forth. It can hold a fountain pen at a proper angle of 45° to the paper. You can also use implements that aren't pens, such as pencils, chalk, charcoal, brushes, styluses on touchscreens, and many others. However, take note that AxiDraw is generally recommended for use with instruments such as fountain pens and rollerball pens, which do not require the user to apply pressure.
Unlike other models of AxiDraw, the AxiDraw MiniKit 2 is a do-it-yourself kit that needs to be built prior to use. Assembly is straightforward with the comprehensive and highly illustrated instruction manual, which is provided as as a PDF download. You will need to provide certain tools for assembly: Scissors, and small Phillips head and flat head screwdrivers. No soldering is required.
Once you've finished building the AxiDraw MiniKit 2, the comprehensive AxiDraw user guide walks you through every step of using the machine.
To operate AxiDraw, you will need a reasonably modern computer with an available USB port, plus internet access to download necessary software. Pens and paper are not included. (You can use your own! AxiDraw does not require proprietary pens or paper.)
AxiDraw is normally controlled through a set of extensions to Inkscape, the excellent, popular and free vector graphics program. Basic operation is much like that of a printer driver: you import or make a drawing in Inkscape, and use the extensions to plot your text or artwork. It's all handled through a straightforward graphical user interface, and works cleanly on Mac, Windows and Linux. Additional software interfaces available to AxiDraw owners include AxiDraw Merge, for auto-populating documents with data sourced from a CSV spreadsheet file.
