Result
Good contrast and details. Not sure how durable it is, but it doesn’t wash out with water or alcohol.
Lessons Learned
Sharpie. Painting the surface with a black sharpie before engraving gave a darker marking on the aluminum. Did multiple test on red anodized aluminum, and the sharpie did a significant difference for same speed and power. Aluminum pieces should be painted with sharpie before engraving.
