While the Othermill is optimized for milling circuit boards, it can mill a whole lot more! With proper bit selection, you can mill the following materials:
We have incorporated high performance parts into our design wherever possible. For instance, each linear actuator consists of a stepper motor that is rigidly coupled to a teflon-coated lead screw with an anti-backlash, wear-compensating nut that requires no lubrication and has a long, low-maintenance life. This means you won't have to worry about your parts breaking down just as you are getting into your project.
Our low-vibration, high speed spindle and precision lead screws allow you to reliably cut 10 mil trace and space on FR-1 PCB stock. Any tool with a 1/8" shank can be used with the Othermill, including all Dremel and Foredom Flex-Shaft accessories. Create custom circuits that fit into odd 3D printed parts, integrate seamlessly into clothing, and free up your Arduino for another project.
We believe that the software interfaces for CNC machines should elicit joyful user experiences. For this reason, we focus on designing the CAM for the Othermill to be WYSIWYM - what you see is what you make.
We use TinyG, an open source motion controller from Synthetos. This means you can use our software, or get adventurous and use your own custom CAM package. TinyG has a built in g-code interpreter, which offloads motor synchronization and timing from your computer, ensuring accurate control even while you're checking your mail.
The Othermill is designed to machine parts with repeatable quality, day after day, but at 16 pounds and 10" x 10" x 12", it's small and light enough to carry with you. It even has handles. You can always grab it and take it on the bus, toss it in your trunk, or put it in your bike basket on your way to the shop or workspace.

When we designed the Othermill, we made a number of careful decisions about materials, construction, and components. We wanted to produce a machine that would be easy to use, but output high quality parts. The Othermill stands out in appearance, because it is made from high density polyethylene (HDPE). HDPE is chemical resistant and moisture proof, leading to a longer lasting machine.
When we realized that we could make molds using the mill, we went straight for chocolate. The positive for the molds was milled out of machining wax, and the molds themselves were made from silicone. Machining wax is a great material, and it machines like butter.
Once we had the molds, we just melted molding chocolate, which you can get from most cooking/pastry supply stores. You can find more complete instructions on our blog. A similar process can be used to mold almost anything: ice, silver, clay, whatever.
3D printers are amazing, and hardly a day goes by that we don't hear about a new use for them. Still, there are a lot of things 3D printers can't do, and that's where a mill comes in!
The real fun starts when you put your milled parts with your 3D printed parts. When you have the ability to combine any shaped enclosure with any shaped circuit board, you have a world of custom electronic gadgets at your fingertips. We can't wait to see what you'll make!
We're huge fans of mixing technology and fashion here at Otherfab. The very first circuit we cut out on the Othermill was a tiny carrier board for haptic vibrating motors. Sewn into a GPS enabled jacket, it can tap the wearer on the shoulder as they walk around. With the freedom to make sewable boards, your designs can explore even more interesting directions!
Desktop manufacturing is like industrial manufacturing, but on a smaller scale. Manufacturing is the art of making objects and parts and devices, and in the modern industrial world, this is accomplished with the assistance of computer numerical controlled (CNC) machines. Decreases in the cost of motor control and advances in computer software have led to the development of small CNC machines (desktop) that have the same capabilities as their larger, industrial manufacturing machine counterparts.
You can make anything. You can design things that don't yet exist, and desktop manufacturing tools give you the ability to make them yourself. Like the desktop printing revolution of the early '90s, we are at the edge of a monumental shift towards technologies that used to be out of reach.
The DIY movement has inspired a generation of people to think outside of the big box store and to create their own products. People are now creating their own tools, toys, clothes, transportation, books, and digital music. Desktop manufacturing expands the wealth of opportunities that will we have for making our ideas real and making them personal and in a way that is repeatable with good quality.
Computer control of machines means that parts can be made much faster with much more repeatable results. Additionally, when you have the ability to make your own circuit boards, at home, without having to use a mail order service for prototypes, you can iterate much faster. Without week or month-long delays, you can afford to be more adventurous with designs and get to a working project more efficiently.
The value of prototyping big things at small scale not only saves you time in the long run, but also saves you money on shipping for mail-order parts. When you are ready for manufacturing large-scale things, it makes sense to work out of a machine shop, but the more you can do at home on your desktop, the more money you will save.
A mill is a machine that uses a rotating tool to move across material and cut out pieces. It cuts very thin layers of material at a time. This allows it to create a detailed design.
The Othermill is a small, computer controlled, 3-axis mill that is specifically designed for use at home or in a small workspace. Our objective is to build a mill that is small, clean and quiet enough for use at home, and precise enough for high level electrical and mechanical prototyping work. We want the Othermill to feel at home on your desk, in your workshop, or on your kitchen table.
With our mill, you can produce custom circuit boards quickly and cheaply: make all your projects light up, beep and move. Wearable circuits, custom guitar effects pedals, quadcopter electronics are all within reach without having to wait for boards to come back from the manufacturer. Over time, this machine pays for itself in not only time but money saved on mail order boards. Even though the Othermill is optimized for cutting circuit boards, it can also cut metal, wood, wax, and plastic. It is great for engraving and milling 3D shapes for jewelry or toy making.
The Othermill is smaller, higher precision, and cuts a wider variety of materials than any other small-scale mill on the market. Our machine and our software are also designed to integrate as seamlessly as possible.
The Othermill comes with a custom application called Othercam that is designed with a 'what you see is what you make' mindset. We have experienced all sorts of difficult and frustrating CNC machine user interfaces in our time, and so we care about making our machines as easy to use as possible. However, our machine also supports industry standard G-Code. Any CAM processor that outputs G-Code in arcs/mm will work.
Othercam runs on MacOS X Lion (10.7) or higher. However, you can run other CAM interface programs such as Synthetos tgFX, for more information see Synthetos on github.
We offer a 90 day warranty. You will receive a working machine and if anything goes wrong, contact us through our support email address and we will help as best we can. Because the machine cuts metal and plastic, and is made out of metal and plastic, it is capable of destorying itself if told to do so. Our software will do its best help the operator avoid this, but sometimes mistakes happen. We will do our best to help keep you up and running.
The cut volume is 6" x 5" x 1.4".
The Othermill fits all 1/8" shank bits, including all Dremel and Foredom Flex Shaft accessories.
Cutting time varies based upon the material and the complexity of the part you are cutting. We have cut out Arduino shields in around 20 minutes.
The precision carbide endmills will eventually become dull. We will be offering them for sale on our website, and they can be found at good hardware stores, both on and offline.
