X axis assembly

Assemble the C beam with the rack and linear guides like in the previous step, and add 2 linear bearings per linear guide, but do not use the technique to push the 2040 rail into the C beam – rather keep the 2040 rails as a support rail to sit behind the C beam and to act as a support for the drag chain.

And then add the 2 Y plates – with the rack facing the front of the machine:

Again, you can use M5 x 12 mm or M5 x 15 mm screws to attach

The assembled X axis can then be attached to the linear bearings on the Y axis, via M4 x 14mm screws
