Okay, several things learned here. First, it validates the above post, second, on the right we see that for engraving we have to pay attention to the QR until it gets integrated into the masking., Third, we see why for a nice engrave you want to prep an SVG file instead of just lifting a jpg like I did. I did this on second to lightest and if I’d been one darker it would have done some damage to the no burn zones. In an SVG those could be excluded altogether not just lightest.
None the less, I’m impressed. Thanx @mpipes
