I have been looking for lasers, i have found a few however i now have a problem. I am looking to engrave something with varying thickness. Will autofocus be able to compensate? The second problem is. The thing I want to engrave are about 1 to 2 inches thick. I dont believe most lasers will go up high enough...what do i do? =(
Finally. How much power do i need to engrave anodized aluminum?? How about to cut 1/2 acrylic?
