Step 4 - CNC Z-Axis Part 2

UPDATE: The back of the z-axis in the third video was measured 5.5"; however, since I chamfered the corners of the rail section of the z-axis to secure the aluminum angles, the length of the z-axis back was shortened. In the fourth video all of this is explained, and a convenient way to measure the correct length yourself since everyone's widths will vary. The missing component that wasn't covered in the part 1 of this step was the z-axis rail (using aluminum angles instead of round bars) and the z-axis rail support. In addition, the back of the z-axis was re measured in a more logical way.
