What is CNC?
A CNC is essentially a machine that is controlled by a computer and can perform highly intricate maneuvers over and over again (similar to a printer). In this case instead of dispensing ink onto the paper, it uses a cutting tool to cut very detailed shapes into common materials like wood, plastic, & aluminum. It is a critical machine in any manufacturing factory, or research and development lab. We think it’s a tool that will be found in every workshop and home garage in the future.
We want to make that future a reality!
In August 2010 we pitched an idea to University of Minnesota staff to create a challenge for five graduating seniors in the field of Mechanical Engineering. We wanted the students to come up with an affordable, accurate and fast CNC machine that could make automated manufacture available to everyone. We wanted a design that was modular, one that could be taken apart changed upgraded and modified with very little mechanical knowledge. Most importantly we wanted a machine that once built, could manufacture additional machines. Thus creating a scalable array of machines building other machines to make production simple. We worked closely with the students for months as we all worked together to come up with a design that we feel is so good, so perfect, that we all want to step forward and offer it to everyone here on Kickstarter.
Our CNC Machine is 26” by 20” with a useable cutting area of 18” x 12”. It is designed using only the best linear motion components and is made to be as robust as possible. The frame was designed to be very rigid while using techniques make assembly a breeze. You could very easily disassemble and reassemble the machine in a matter of minutes using simple hand tools. The Z-Axis (the one that moves up and down) has a modular bolt pattern that can accept a wide variety of cutting tools ranging from a Dremel to routers, even lasers and plastic extruders. This is no cheap machine either. It uses hundreds of dollars worth of shafts, bushings, bearings and professional leadscrews to get it moving! In fact, 80% of the machines’ cost is in these expensive linear motion components. To put it simply, this machine is awesome!
One of the benefits of being designed by engineers means that we have already scrutinized every aspect in the prototype of our design. It was run through a battery of tests while reports were being written. We found any areas where we could improve and made changes. Our next steps really are only to figure out exactly how to use our CNC prototype to manufacture potentially hundreds more of our CNC design! For a video of our prototype in action, please check out the video at the top of the page.
It is important to know that in order to make this project succeed. We need to have our goal met. If you think we have a cool project, please pledge any amount. We appreciate whatever you are able to provide us with. We also have some wonderful rewards the best of them being completed CNC kits!
At this level we would love your support. We have some stickers and brochures that show our machine and explain the design process. They may not be much, but at this level pledging means the most monetary support!
The first cuts our machine made were to cut out a 10" x 10" gear into the table surface of our machine. It is a very complex piece to cut, and would be very complicated to do without a CNC machine. At this level we would love to send you a copy of this gear, cut from MDF wood. It would make a great piece to paint and hang on a wall!
At this level we want to show off our machine's ability to engrave. We want to create some lithophanes on acrylic plastic. For examples of what a lithophane looks like, see here. We will take any photo that you provide us (portraits, landscapes, or logos) and use our CNC machine to engrave the photo into a lithophane. It is a very complex task that would be near impossible without a CNC!
At this level you get a CNC kit at a discount! This level gets you a full kit that you will need to assemble. Each kit is put together and parts tested before shipping. The kit includes all the support pieces, all the fasteners, and all the linear motion components. That includes steel polished rails with Oilite bushings, ACME leadscrews with acetal nuts, and precision bearings. Includes a Dremel 300 tool holder that will allow you to install your Dremel (not included). Shipping in the United States is included in the price. International backers please contact us for a shipping quote.
At this level you will receive our base machine as described at the $550 level. In addition you will receive an electronics box and NEMA 23 motors to run the machine. The motors and controller are all pre-wired and requires only a simple plug in and go. Also included are a Bosch Colt router, and a Bosch router mount. Includes a full version of commercial CAM software. Shipping in the United States is included in the price. International backers please contact us for a quote. NOTE: That international pledges will need to open the electronics and switch from 110v to 220v.
At this level you will receive everything at the $1050 level (a machine, electronics, motors, and Bosch router), and a Dell Desktop computer preloaded with a paid version of Mach3 to control the CNC, and a full version of commercial CAM software. This is very much the closest to Ready to Run that you can get. The machine will require assembly, but everything else will just plug together and within a few clicks you will be ready to go. Shipping in the United States is included in the price. International backers please contact us for a quote. This is a limited reward to 5.
What Makes it Better?
The number one question we have gotten while talking about the CNC design is: What makes it better than the other machines out there?
Our machine was designed by five engineering students under the supervision of a Mechanical Engineer. It was designed using brand new and highly precise linear components from industrial suppliers. It features polished steel linear rails, and slides on bronze metal "Oilite" bushings for smooth operation. The mechanical screws are high precision multi-start leadscrews, designed to convert rotary motion into linear motion. We don't use cheap off the shelf threaded rod like other machines out there. Because of the multi-start leadscrews, our machine is able to move at great speed. We were able to get our prototype to move rapidly (and repeatedly) at over 200 inches per minute, which is lightning fast! Our modular design allows for all kinds of parts and add-ons ranging from different cutting tools, to different work surfaces and more. This is all from a machine that takes up a very small footprint. It is able to sit on a desk, and yet it has a very large cutting area for its size.
And let’s not forget cost! Other CNC machines of this size and power are thousands of dollars. This machine finally brings affordable CNC automated machining to the hobbyist.
On behalf of the whole team. Thank you for taking the time to check out our project, and we all hope you enjoy our CNC machine and will help make our dreams into a reality.
