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.

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.



Tools required:


Pro Tip:

  • Don’t forget to slide the Gantry onto the V-Slot before you attach both Actuator Pulley Plates.
  • Don’t forget to attach the Timing Pulley to the Nema17B Motor shaft before attaching the Motor to the Plate.
  • Follow this process for correct tensioning the GT2 Belt:
    1. Tighten the screws on one Actuator Pulley Plate to secure the Plate in position.
    2. Feed the Belt over the Pulleys and through the hollow center of the V-Slot
    3. Pull the other Actuator Pulley Plate away to Tension the GT2 Belt, tighten the screws on the Plate while it is under tension
    4. Tie or Clamp the GT2 Belt on both sides of the Gantry
