So in my standard production of “death frames” for my wife’s animal hospital, I crank through about 20 of these frames at a time. I have magnets on the bed and I just engrave, open, put a blank one in and hit print without changes. So bizarrely one of them did a partial engrave (ignoring all but 2 complete letters???) No idea how letters in their entirety got engraved and other letters got forgotten (this was the 14th in line so I know the file is good)
The one above is the prior one that just came out and the fail is the lower.
