Important Pre-Assembly Notes
Before starting your build, we suggest taking a minute to read through the assembly guide so you can get an idea of how everything fits together. Pay close attention to each step and make sure you understand the instructions before continuing. Also, be mindful when attaching parts - if it feels like you're having to put a lot of force into it, stop, re-read the instructions, and try again. Don't over-tighten screws - doing so may strip the thread or head. If you have any questions about the build, don't hesitate to reach out to us. You can chat with us live on the store website or email us at contactus@imakerstore.com - we're here to help!
We value your time, that's why we ship our products with pre-assembled subassemblies like wheel kits and gantry carts to make your build process faster and simpler. Need help with our products?

Follow the below steps for the linear actuator assembly
Step1: Wheel Assembly: Check assembly instructions here
Step2: Pulley Wheel Assembly: Check assembly instructions here
Step3: Gantry Assembly: Check assembly instructions here
Step4: Idler pulley end plate assembly
It is easy to assemble the M5x8 screws and M5 tee nuts on the plate. However, do not tighten them as these are used for fixing the sub-assembly to the V-slot rail. The M5x25mm screw and M5 nylon lock nut are part of the Idler Pulley Wheel Kit.
Step5: Motor end plate assembly
Follow the image for assembly instructions.
Step6: Attaching gantry cart to V-slot
Note: Make sure the gantry cart runs smoothly along the V-slot rail by adjusting the eccentric spacers.
Step7: Fixing idler pulley end plate assembly to V-slot
Step8: Fixing motor end plate assembly to V-slot
Step9: Attaching belt to the actuator
- Don’t forget to attach the Timing Pulley to the Nema23 Motor shaft before attaching the Motor to the Plate.
- Follow this process for correct tensioning the GT3 Belt:
- Tighten the screws on one Actuator Pulley Plate to secure the Plate in position.
- Feed the Belt over the Pulleys and through the hollow center of the V-Slot
- Tie or Clamp the GT3 Belt on both sides of the Gantry, which has Aluminum spacers at the center for fixing the belt. The belt end could be wrapped around the spacers and then use zip ties or clamps to tie the belt.
- Pull the other Actuator Pulley Plate away to Tension the GT3 Belt, and tighten the screws on the Plate while it is under tension
