machinesformakers.com lists xTool F1 Lite (also 2W class) black anodized aluminum at 150mm/s 40% power. Scaling to full 100% power may allow slightly faster speed; start at 150mm/s and test. One of the better use cases for the 2W fiber. | Freq: 50kHz, line interval: 0.05mm

Creates bright white/silver mark on black anodize. Short ns pulse critical. Same approach as general anodized Al but maximise power to ensure full coat ablation in one pass. LightBurn material library listings for B6 30W confirm this range. | Freq: 55kHz, pulse: 4ns, line interval: 0.04mm

White/light mark on black anodize. Short pulse + high frequency key for contrast without charring. 30W reference from barchlaser.com scaled down for 20W (reduce speed by ~25%). Very common for dog tags and ID plates. | Freq: 55kHz, pulse: 4ns, line interval: 0.04mm
