X axis binding at each edge. Video included

I thought I had fixed this problem, but I found the root cause of my issue with the X-axis losing steps. The X-axis is binding at each end, causing it to lose step when it’s brought to the X limits.

I made a video illustrating the issue and note that the X Stepper motor was removed during testing, as you can see from this photo.

Does anyone know what can be causing this binding when the bracket that holds the lead screw is fully tightened?

Thank you in advance for any help.

Thank you, William. I could not find the PDF, but I found the video, which provided guidance about adjusting the bolts attaching the Z carriage to the linear bearing at several points along the axis, and this fixed the binding issue. The machine is back together and upon jogging the x axis to the both ends it no longer binds.

Thanks again.
