Instructions with some images for more clarity.
Bambu does a nice job describing steps to put text on parts. Please follow these to add text.

For this example I created three different text components. Just to show the difference of how the program slices each one.
Steps to make text flush.
After creating your text on the part, left click on the text in the panel on the left hand side.
Right click and select change type
select modifier
after slicing, should look like this
In this setup all of the text have the same setup
the only differences are the type specified:
“YOUR” Is default set to part
“TEXT” is set to negative part
“FLUSH” is set to modifier
I like to use an embedded depth of at least 3 layers or 0.6 that gives enough filament to make it clear and the correct color. Depending on color differences 1 layer with a light color and a dark background will actually alter what the color looks like.
change filament color if you are not familiar, this will make the entire text colored in that filament
One caveat that I have to mention:
For whatever reason once you change it to modifier, you can no longer edit text (edit text is grayed out). To edit the text switch it back to negative or positive part, then select edit text. Once edits are made switch it back to modifier. A bit of a pain but still better than always trying to have to adjust the z height and getting it flush, hoping it stays flush, hoping it slices correctly etc. This is a minor inconvenience as far as I am concerned.
Happy Printing!
