Z axis not retracting enough

I had the same

I did check those and the seem to be tight(i was not able to tighten them any more)

This is why it took me so long to find the problem. Because they appeared very tight, and could not see movement I was looking for something else. I think that I removed the Z limit sensor plate and carefully looked at the shaft while I moved the Z with manual commands in CM. It was then that I noticed the 1/8 turn slip in the Z gear that was causing me all the grief for over a week.
