Engraving from Fusion 360

Hi,

I have set up a few engraving jobs from Fusion 360, until lately they have not been successful. The F360 preview looks good, and the importing of the g-code into easel seems to go ok. I use the probe method to set the material thickness. But the finer details of the engraving are lost, for instance the serifs of letters. I finally used a manual setting of the height to be about -.015 inches and it finally looked good. Is the pointed v-groove getting a false height setting?
