This kit utilises standard v-slot parts to create a very simple but powerful belt driven linear actuator. The belt driven linear actuator takes advantage of the v groove and uses the precise and strong delrin solid v wheels for smooth linear motion. The linear actuator can be used for a whole host of applications, from a simple camera slider, to a modular 3D Printer design.
Because this kit uses all standard v-slot parts it can be easily combined with more of these actuators, other types, or a design of your own to quickly build a functional machine.
We have a range of options available for this linear actuator, it is available in profiles of 20x40mm, 20x60mm & 20x80mm.
In addition to the rail options, we also have the option between the small v-slot gantry plate, or the full size v-slot gantry plate. If you choose the full size v-slot gantry plate you have the option to have 6 delrin solid v wheels instead of 4 that is used on the smaller plate.
With the small v-slot gantry plate the travel of the actuator is 85mm less than the extrusion length. For the full size v-slot gantry plate the travel of the actuator is 110mm less than the extrusion length.
For the motor there are multiple of options available. The first option is to have the linear actuator without a stepper motor, if you choose this option the hardware to mount the motor, and motion parts are still provided.
The second option is a stepper motor included. Stepper motors ideally need to be run from a controller with a stepper driver, the controller is not included with this option.
The final option is a stepper motor with a uStepper controller. The uStepper is an ultra compact stepper motor controller board, it is Arduino compatible with a built in stepper driver, it can be mounted directly on to the back of the stepper motor. In addition to this it also has a 12bit rotary encoder, this allows absolute position tracking of the motor shaft making missed stepped detection possible. The uStepper also has a built in temperature sensor next to the stepper driver, allowing for continuous temperature monitoring.
The uStepper needs to be programmed through the Arduino IDE to carry out the operations you require. To simplify this an Arduino library is available for uStepper which provides functions for all the main features.
The EGO Shield for the uStepper, is a 4 push button integrated OLED Screen shield for the uStepper. This allows basic control of the actuator without progamming knowledge. See related products below to find out more.

Minimal tools are needed, 4/2.5/1.5mm allen keys, 8mm Spanner, and Scissors.
This is a very simple kit to build. Mark Carew, of Openbuilds, has made an excellent instruction video showing you how to build this linear actuator. This video can be found in the tab named “Documentation” directly under the thumbnail pictures above
what you will be getting
Everything to build a belt driven linear actuator as to Mark Carew’s specification, with the options chosen above. A NEMA17 stepper motor is an optional addition, if you choose not to have a NEMA17 stepper motor, you will still get the mounting hardware, belt, and pulley.
