Help Needed Setting Up Auto Focus

I spent some more time last night trying to get the focus correct. I tried several different setting and step sizes, but ended up pretty much where I started with the settings. I took a few screen shots in case it helps.

I've never used autofocus before, so I'm not sure exactly what to expect when compared to focusing with the Bahtinov mask.

Before I started auto focus, I focused using a Bahtinov mask.

After it finished, I got this message.

Here is what the graph looked like.

After autofocus I checked it again with the Bahtinov mask. Focus is off compared to before autofocus.
