SparkFun Stepoko Motion Control Add-On Kit

Need a bit more than just a SparkFun Stepoko controller? The Stepoko Motion Control Add-On Kit provides you with everything you need to get your CNC moving, powered, and controlled. This add-on will allow you to convert a simple mechanical kit into a full CNC machine! Inside each kit you will find our SparkFun Stepoko board, four NEMA23 stepper motors, an enclosure milled to hold the Stepoko, a 24V/5A power supply, a toggle switch, and 6ft A-B USB cable. Just add your own rig (like the Shapeoko 3) and you are ready to get started.

The included SparkFun Stepoko is an Arduino compatible, 3-axis control solution with pre-installed grbl software and is able to connect to your computer to accept stepper motor commands. Additionally, the four stepper motors found in this kit are ideal for CNC projects by offering 125 oz.in of torque, 200 steps/rev, and adhere to a NEMA23 form factor. This new revision updates the firmware on the Stepoko board to the latest version (0.9j). We’ve also added a piece of thermal gap filler to help electrically insulate the board from your chassis and prevent problems from ESD, and some cable carriers for cable wrangling.

Note: This kit does NOT come with a power cable to connect the power supply to your specific wall outlet. This way you will be able to use your own cable that fits your country’s national standard.

Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

4 Robotics

Skill Level: Experienced - Your experiences should include working with stepper motors and feedback system. You may need to understand how encoders and more complex control systems work.
See all skill levels


Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

2 DIY

Skill Level: Rookie - Basic hand tools are required and instructions will allow more freedom. You may need to make your own decisions on design. If sewing is required, it will be free-form.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Customer Comments

  • I’m a little unclear why a 3-axis controller comes with 4 stepper motors. It’s like hot dogs and buns.

    • It’s difficult to drive most gantries along the Y-axis w/ a single motor — the original Shapeoko did this, but it was a problem for a lot of people, hence:

      but c.f., http://www.shapeoko.com/wiki/index.php/Drive_Shaft

    • That’s a really good analogy!

      This kit is general purpose, so you could use two on a single axis (like the shapeoko), or have a spare.

  • Can the enclosure house both the Stepoko board and a RaspberryPI board?
