DIY CNC X-axis assembly detail
These are the details for assembly of the X-axis carriage.
- Major components bolt together
- Use two nuts at each end of the threaded rod and “double nut” them.
- An Acorn Nut on the side of the threaded rod opposite the stepper is only for aesthetic purposes and to shield what can be a sharp and rough end on the rod.
- It is critical all components are square during cutting and at assembly
- When mounting the X-Axis assembly to the rails on the base, you may need to shim under the X-Axis Linear Bearings (#5) to get a snug fit (I used business card stock)
- The Linear Bearing Nut (18) is shown here, but must be installed on the Z-axis assembly before it is threaded onto the threaded rod (12)
- The two aluminum angles (16) are held in place by the Z-axis assembly. Hold in place with some masking tape during assembly.
