With the upper-burr-holder all the way down, reverse direction on the grind-adjuster and rotate through 50% to 75% of a rotation.

Stop when the stop-screw is right above the plastic stop shown in the first picture.

The lip should be about the height shown in the first and second pic. That's critical for your grind to match up with the labeling on the chrome-adjustment wheel after this is all done.

Compare the lip height with the photo you took in Step 11. Make sure the gap looks the same.

Screw the stop-screw back in.

Optional Modification: If you desire a finer grind capability than normal, mark the original stop-screw hole, and then move the stop-screw a few holes clockwise. Then rotate the upper-burr-holder counter-clockwise till the screw hits the stop again. Make extra sure the burrs do not touch if you do this!
