Text on Text Problems

I posted that I was having trouble with Text on Text a couple of weeks ago and was given this link:

I went through the second updated 2020 tutorial very carefully and downloaded the file that was attached. I used the same feeds and speeds and thought I did everything exactly the same, but mine does not look nearly as crisp. 1/4" seems really deep, too.
Also the parts about inside offsets and boolean subtract for missing geometry lost me completely.
