Our project is to build a set of CNC components that can easily be assembled in many different ways to create one incredible machine.

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, & metal. 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 WILL make that future a reality!

The Pitch

Our previous project was the Modular Desktop CNC Machine here on Kickstarter. We learned a lot from doing that project and took what we learned to create these new parts. What we found was that professional linear components cost hundreds of dollars. Most DIY CNC machines use bearings on bolts, or drawer slides or other various hardware store concoctions of parts, but these parts aren’t very accurate or precise. Our dream is to change that. We want to make our own DIY CNC system that offers hundreds of dollars worth of parts in a simple affordable package without sacrificing quality. That’s why we created the CNC Building Blocks.

Additionally we discovered the limitations with current offerings of CNC electronics. They were either: overpriced, underpowered, or overly complicated. We have taken the bare essentials (yet, enough features for any hobby CNC machine) and built them all onto one easy to assemble board.

The Project

We are making a set of CNC building blocks. Blocks that can be assembled in many different ways to create a CNC system that is capable of engraving, milling, routing, cutting, or rapid prototyping. These blocks are high quality plastic injection molded parts.

There is a Z-Axis, which also integrates the Y-axis movement into one single component. The Z-axis has 3" of travel and uses ACME lead screws with common nuts. All the parts are bolted together, and the plastic parts are injected with brass hardware. The front of the Z-axis has a simple 2" x 1" mounting pattern that will be able to accept a wide range of spindle holder. We'll have them for the Bosch Colt and Dremel... but laser cutters and plastic extruders may be available. The Z-axis is fully assembled and will take all of the hassle out of making one of the most complicated parts of a CNC machine. One is included with the CNC Building Blocks kit.

The Linear Slider is designed to use a standard 3/4" shaft (not included). It has integrated brass bushings that allows for smooth linear motion. The mounting pattern is standard and is common for linear bushings of this size. Four are included in the CNC Building Blocks kit.

The ACME nut holder is crucial for computer controlled movement. It translates the motion from an ACME lead screw into lateral motion. The part includes injected brass hardware to allow for easy installation of the ACME nut (included). There is one included with the CNC Building Blocks kit.

The Shaft holder is the simplest plastic injection molded part, but it plays an important role. It allows for you to install a shaft to any structural component, be it wood, plastic, or metal. A standard 1/4" screw sits in a recess that holds the holder in place, and the shaft installs tightly in the holder. There are eight included with the CNC Building Blocks kit.  

Electronics

While the CNC Electronics are deserving of their own project on Kickstarter, we decided to make them a part of the Building Blocks project. We have developed an amazing, small CNC controller that uses high powered stepper motor controllers. We skipped all the extra features that the common stepper motor controllers use and went straight for simplicity, low cost, and high power... all in a tiny package!

The CNC electronics are based on the SLA7078 chipset by Allegro MicroSystems. They are a chopper style driver, for 5, 6, & 8 wire CNC motors. Fully adjustable between 0.5 - 3.0 amps for stepper motors large and small. With microstepping levels of 1/2, 1/4, 1/8, & 1/16. The chips feature patent pending short & open circuit protection, in case of a mixup during installation or use.

The board is able to take signals and power in, and provide motor control out. Very simple design leaves no extra wires or boards. Plus, onboard voltage regulators provide hook up for a 12volt case fan, and limit switches can be wired into easy to use screw terminals. Available in kit form for $50, with easy assembly instructions, and pre-assmbled for $100. Both prices should be among the most inexpensive boards available, and are being sold at cost here on Kickstarter!

The Prototypes

We’ve already spent tens of thousands of dollars to begin production on these parts. We believe that strongly in them. Our Z-Axis system is already through the prototype stage, and ready for production. Every part is made from high strength ABS plastic that was injection molded around a set of metal hardware.


Our electronics have been developed and tested. They use the Allegro MicroSystems SLA7078 chipset. We have developed them into a board that is just 5.5 inches by 2 inches. One of the smallest, and cheapest CNC controllers available.
