Step 5 - Y-Axis Bearing and Rail Support

This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. We are finally to the y-axis. In this video you will see how I built the y-axis linear bearing support and the rail support. First the rail support is similar to the rail support for the z-axis, but wider. This width carries much of the load and the width determines the z-axis length of travel. If you want more z-axis travel, pick a wider y-axis rail support width. In this case, the width to which I'm referring is the short side of the piece. That is... if you made the z-axis travel longer than the length of the y-axis rail, then the width would be more than the length. Did I confuse you yet? I think I confused myself. Well...let's get on with the build.
