The other matter that no one tells you about is to make sure that the face you are milling for text is true & level.
Slight warps in timber when using ball nose cutters at shallow depths will result in the lettering strokes changing in "pen-stroke" widths.
Solutions include facing off the surface with a rose-type cutter pre-text cutting or buy a floating head for your machine that will maintain a set depth in slightly uneven material.
I have done a fair amount of text in plywood which is notoriously uneven using a floating head system on my machine.
After initial headaches, the text process is now solved.
Note : the floating head I believe is also called a "depth regulator " attachment.
