Limit switch activation question

I am currently in the process of wiring. I see a few other people have had the same problem as me. In what step do the instructions tell you to put the T nuts and screw in for limit switch activation? Am I just not to that point yet?

If I did miss the step, what’s the solution? Undo the self taping screws and insert the T nut?

Those T-Nuts are a “post assembly” type. This means you can install them after the extrusion ends are covered by rocking them in.

Look on this page about 80% down the page.

Thank you so much! I was trying desparately to find of I had missed something. I should have just followed the process! Thank you for explaining.
