Looks great…What settings did you use?
Fun test. Thank you for your settings.
I wonder how much of a difference it makes. All of my AA tags I’ve done at 1000/Full/340 and gotten sharp results.
Next one I do I will try your settings and see if there is a difference
The key for anodized is “enough” power but extra power makes no difference. I always run high speed and high power.
The critical factor for them after power is LPI. This is one where high LPIs make a very real difference. In organic materials you have issues with high LPIs just over-cutting previous lines and sometimes even degrading the end result. With anodized aluminum I’ve found that increasing resolution increases perceived quality all the way up the scale. Where I tend not to go higher than 225 on wood or acrylic, I start at 340 for aluminum and will often oush it higher.
Everything you just stated is exactly what I’ve always believed to be true. 
Same settings I use.
Thanks for the info. Next time I will ramp up the speed
Generally, IMHO, unless there’s some sacrifice of quality, or 1000 doesn’t do the job, I always try to stick with 1000 speedicles. It’s rare I need to slow it down. No need to waste my time.
Speed is also my controlling parameter. I only slow down when full power & 1000 (or 500) doesn’t do what I need.
“I want what I want when I want it!” and slowing down just makes me wait 
I ran a couple more tonight at high speed and high power. Higher LPI. A little cleaner look better speed of job.
Great Idea
I’ve always done 1000/100/340…sort of the same as you. Apparently, anodized aluminum is very user friendly to different settings.
