Random engraved pixels around edges of engraving

These 2 images are both from the same exact engraving, just different font size.

70% power (105 watt tube)
0.070 interval
Single pass

I may be able to fine tune the interval and scan offset a bit, but it seems like I can only optimize one font size while sacrificing the consistency of the other. After a dozen different tests with varying settings for power and interval, I’m finding I can get either the larger text, smaller text, or thin logo to look good, but not all at once.
