Divots in the corners

I’m stumped as well. The issue is happening with both the 1/4
“ inventables v bit and this amana one as well.
I’ll check the backlash now.

So I made the carves deeper .6 for “magic” &
.09 for “ A” and now the divots basically disappeared. I would have thought they would be more pronounced. Might it be a grbl issue?
