Pre-Assembly Notes
1.0 About the C-Beam XY Actuator Kit
The C-Beam XY Actuator Kit is a two axis linear actuator driven by our ACME lead screw.
The kit is an easy way to get all the pieces needed for the build. Sizes available are 250mm, 500mm, 1000mm, 1500mm
C-Beam Actuator Assembly
To build the two C-Beam Actuators required for this kit, please follow the instructions in the manuals below based on the length of your kits C-Beam. When assembling the gantries (section 3), skip to section 3.2 C-Beam XL Gantry.
C-Beam Actuator Kit – 250/500mm
C-Beam Actuator Kit – 1000/1500mm
These actuator assemblies will be referred to as CBA in the following steps.
Joining Actuators
Once you have completed the respective actuator assemblies in the previous section, all that is left is to join the two actuators together.
You will need the following:
Item | Description | Qty |
11 | M5 Low Profile Screws – 12mm | 4 |
CBA | C-Beam Actuator Assembly | 2 |
Regardless of your actuators size, the joining method is the same.
Step 1. Lay one C-Beam Actuator Assembly (CBA) XL Plate down on top of the other XL Plate. Line up the non-threaded holes with the threaded holes as depicted in the images below.


Step 2. Secure the actuator plates together using the 3mm Allan Key

Congratulations! You’ve completed the C-Beam XY Actuator Kit!
