Easycnc has text option built in, a bit blocky if memory serves.
If you put them in the mold I think they will have to be 'backwards' as it were so as to read them positivley if you get my meaning.
I have tried many ways to get a single line text in easycnc but so far have had no luck.
Doing small text using outline is a bit of a time waster as the cutter keeps going over the same ground twice.
Just play and see what you end up with
