so I am trying to assemble a new table. I open my xl kit to install the lower rail. but on the rail it has only 2 mounting locations per side. but on the instruction diagram it shows 4. 2 for z axis kit and 2 for non z axis kit.i do have the z axis kit so was wondering if those mounting locations mattered?
*** I also noticed that my xl kit did not come with items 3 and 4, the lead screw and self tapping screws.
