I'm new to laser and this forum. I have a new artcut 40 and have it to a point where I can engrave a faint outline of text on anodized aluminum at around 12ma. I've tried several speed and cut settings - they don't make much difference. I bought the tags from Chewbarka Tags, and they are supposed to turn white when co2 lasered. I could use some help, and I also can't find where to change the text from outline to filled. Thanks, Kevin
