The EiBotBoard ('EBB') is a USB-based dual stepper motor controller board that is useful for many general purpose robotics applications. Originally designed for the EggBot project, it is the 'brain' of all current models of the EggBot, but also of the AxiDraw and WaterColorBot as well. The EBB was designed by Brian Schmalz of Schmalz Haus LLC. It is an open source (in both hardware and software), PIC18F46J50-based motor controller board. Standard features include two Allegro A4983 16X microstepping motor drivers for bipolar steppers. It also has a separate onboard regulator to power up to two hobby servo motors. It is 2.2 x 2.2 inches square (5.6 x 5.6 cm). We are currently shipping version 2.7 of the EBB, which features several improvements for reliability. Version 2.7 uses a standard USB micro connector and has a switch that by default turns off power to the pen-lift servo motor after one minute of inactivity. You can change the timeout duration or disable this feature using the serial command protocol. Specifications Motor driver ICs: Two Allegro A4983 Stepper motor type: Bipolar (2) Step size: Full, 1/2, 1/4, 1/8, 1/16 Motor connectors: Screw terminal USB jack type: Micro-B Power connector: Barrel Jack, 2.1 x 5.5 mm, center positive Voltage input range: 9-25 V DC Output current adjustment: 46 mA to 1.25 A per phase Downloads/Documentation GitHub
As compared to the (US Letter/A4 sized) AxiDraw V3, the AxiDraw V3/A3 has extended travel range, designed for use with paper sizes up to and including 11 × 17 inch ('tabloid' or 'ledger') and A3. It can work with any paper up to and including that size, including envelopes, regular US letter (8 1/2 × 11 inch) or A4 (297 × 210 mm) sized paper, note cards, business cards, or a whole array of smaller items. The AxiDraw comes with a mounting easel (board with clips) that can be used for holding paper, cards, and envelopes of various sizes. The AxiDraw V3/A3 also comes standard with AxiDraw Outrigger Feet pre-installed, for greater stance and stability while plotting. The unique design of the AxiDraw features a drawing head that extends beyond the body of the machine, making it possible to also draw on flat objects bigger than the machine itself. For example, you can set it right on top of a box to write an address or add decorations. You can even set it on top of a poster board, chalkboard, or whiteboard to draw graphics in place. The pen holder 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 even 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, and many others. However, you'll get the best results with instruments such as fountain pens and rollerball pens, which do not require the user to apply pressure. Getting Started The AxiDraw comes fully assembled, tested, and ready to use, right out of the box. A universal-input plug-in power supply is included with the AxiDraw, as is a USB cable, and an optional paper-holding easel. Assuming that you've installed the software first, you can be up and plotting within minutes of opening the box. The comprehensive PDF user guide walks you through every step of the process. To operate AxiDraw, you will need a reasonably modern computer with an available USB port (Mac, Windows or Linux), 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.

The V-One Drill attachment will perforate your substrate but won't make it through this layer so your heated bed stays intact. Only one is included, but don't worry, the sacrifical layer can be reused plenty of times.
This is the standard AxiDraw pen clip that is included with current-generation AxiDraw V3 family plotters. It fits pens and other instruments up to 5/8' (16 mm) in diameter. It includes a black nylon 8-32 thumbscrew for holding the pen in place, as well as spare mounting screws. You may wish to get this as a replacement, as a spare, or to have multiple pen clips for custom applications. Compatibility The pen clip is compatible only with AxiDraw V3 family pen plotters that mount the pen on a 2-hole vertical slide. This includes all AxiDraw SE/A3, AxiDraw V3/A3, AxiDraw V3 XLX, AxiDraw MiniKit, and all AxiDraw V3 units manufactured after February 2017.
The set of magnets and spring clips is designed for use with the AxiDraw magnetic easel boards for letter/A4 and tabloid/A3 sizes, but can be used with almost any magnetic surface. The set includes a pair of special spring clips with magnetic bases, as well as six skinny magnets for holding down paper. The two special spring clips each have two curved tines that apply gentle pressure to your paper. They allow you to slide paper directly in and out, quickly and easily, without touching any magnets, clips, or tape. They have a long reach to be positioned behind the rulers on our magnetic easels. Magnetic bases allow you to position them where needed. Two of these spring clips provide just enough pressure to keep a sheet of paper steady while you write or draw on it. This set also includes six cylindrical magnets, 4 mm in diameter and 10 mm tall, which are easy to position and firmly hold paper. The tall aspect ratio makes them particularly easy to grasp (unlike disc magnets). Perhaps more importantly, they tend to yield and tip over if hit by an errant pen tip, rather than holding so fast as to damage your pen or move your paper.
The AxiDraw SE/A3 has the same extended plotting area as the AxiDraw V3/A3. 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.Beyond this, the central beam and X-axis of the AxiDraw SE/A3 feature an all-new geometry for the rolling wheels, which provides more stable and uniform motion along the axis.Getting StartedThe AxiDraw comes fully assembled, tested, and ready to use, right out of the box.

The AxiDraw's pen holder normally holds the pen parallel to the front face of the vertical pen slide, either vertically or at 45° from vertical. This heavy-gauge aluminum adapter sits between the front face of the vertical slide and the pen clip, and serves to rotate the pen tip an additional 45°, not from vertical but out from parallel to the front face of the vertical slide. This gives the AxiDraw the ability to hold a pen in a 'right handed' grip, as opposed to the normal 'center-handed' (for lack of a better description) position. The right-handed grip makes it possible to hold the pen at a consistent angle suitable for use with regular pens, but also stub, italic, parallel, and chisel-point pens. Compatibility This adapter is compatible only with AxiDraw V3 family pen plotters that mount the pen on a 2-hole vertical slide. This includes all AxiDraw V3/A3 and AxiDraw V3 XLX units, and all AxiDraw V3 units manufactured after February 2017.
The mini single pressure sensor gives you an analog read that maps to force on the sensor. The more you press, the lower the resistance goes, perfect for on-body pressure related sensing like ribcage expansion for breathing. This little one is small, but mighty, making it convenient for small surface area applications.

A set of high precision drill bits, covering the most common drill bit sizes. Just pop them in the V-One Drill with a 2.5 mm hex key (not included) and start drilling. The following sizes are included (2 of each): 0.70 mm 0.80 mm 0.90 mm 1.00 mm 1.60 mm
If you are going to be drilling, we recommend drilling on FR1 substrates. Unlike FR4, FR1 dust does not contain fiber glass. It is also a softer material, which means a less wear and tear on the drill bits. Download the template and incorporate them into your design here. 10 substrates included.
When you start to run out of space in your design, migrate over from the small substrates to these. These substrates are made of FR1 – which means they don't contain fibreglass. There is less wear on the drill bits. Download the template and incorporate them into your design here. 6 substrates included.
This rigid end effector plate is designed to be in place of the standard AxiDraw pen-lift Z stage, and provides an alternative mounting scheme for mounting various things to the end of the AxiDraw's arm, for applications where greater rigidity is important but the lifting ability of the standard Z stage is not required. The rigid end effector is custom machined from aluminum, and provides six M3 tapped holes and two M4 tapped holes for mounting what ever it is that you would like to mount to the end of the AxiDraw, to use it as a 2D robot arm. The hole pattern is compatible with the AxiDraw pen clip, so you can, if you like, mount the AxiDraw's pen clip to this end effector. Installation is straightforward, but requires a Pozidrive PZ2 screwdriver, not included*. Remove the AxiDraw's pen clip, and then remove the pen-lift Z stage by removing two screws with the PZ2 screwdriver. Install the rigid end effector plate in its place, using the two included mounting screws and the PZ2 screwdriver. You may wish to also tie back or fully remove the AxiDraw's cable guides, which normally extend to power the pen-lift stage.

This pair of extended 'outrigger' feet for AxiDraw V3 and AxiDraw V3 XLX consists of a pair of machined aluminum struts with large 1/2' diameter (12 mm) rubber foot pads set securely in recesses. It greatly increases the effective base area of the AxiDraw, making it much more stable when plotting, and capable of carrying heavier tools without worry of tipping over. In addition to providing a larger footprint, the outrigger feet also provide four mounting holes that make it easier to secure your AxiDraw to a surface, should you choose to do so. Each foot strut has two top-side accessible #8/M4 clearance holes. Installation is straightforward: Remove the two screws that hold the standard foot plates to the bottom of the AxiDraw, and attach these struts in their place with the included screws. Compatible with: AxiDraw V3 AxiDraw V3 XLX
The Letter/A4 size Magnetic Easel is a sturdy work-holding tool that provides an alternative method of positioning paper or other workpieces for use with the AxiDraw. A heavy-duty alternative to the regular clip easel, it can be used with binder clips or the (included) positioning rulers and magnets. The base of the easel is a heavy-gauge sheet of magnetic steel. It has a powder-coat finish, lightly textured to help hold paper in place and light gray in color for visible contrast against most types of paper. Rubber bumpers on the bottom side (along with the weight of the steel) ensure a no-slip grip on your work table. To help index your paper in a consistent and reproducible position, the easel includes two six-inch (15 cm) rulers that you can rest your paper up against. The rulers are easy to remove and reversible, with inch and centimeter markings on the two sides. They can also be removed completely if you like, leaving just a flat sheet of steel (with a few ruler-mounting holes in it). This easel also includes six cylindrical magnets, 4 mm in diameter and 10 mm tall, that you can use to hold your paper down firmly. Their size and shape make them particularly easy to grasp and position (unlike, for example, disc magnets). Perhaps more importantly, they tend to yield and tip over if hit by an errant pen tip, rather than holding so fast as to damage your pen or move your paper. An optional set of paper holding clips can be added as well if you so choose. Overall dimensions: 12.875 × 9.580' (32.7 × 24.3 cm) Suitable for use with A4 and US letter paper sizes, envelopes, and smaller sizes of paper.
Like the mini pressure sensor, but bigger! Our 3x3 mega pressure matrix has 6 leads, allowing you to map which point you are at in the 3x3 matrix and get a pressure mapping over a surface. Each area has an analog readout that varies depending on the weight of the item on the pressure sensor. Generally, sensor values will read from 500 Kohms to 100 ohms depending on the force put onto the sensor. Features Component: 5' x 6.5 Sensing Area 3.0' Square Thickness: Approx 20 mils
