I feel like I have hit a wall in my research, so hopefully you guys can help me out to give me additional ideas/topics to read up on.
What I am looking to do is be able to etch / engrave primarily aluminum and possibly steel to a depth of roughly .005" or a few thousandths more than that. What type of laser engraver heads and power/wattage levels should I be looking into to accomplish engraving on metal to that depth? From what I have researched, it seems like galvo is the way to go for me and power range maybe around 80 watts?
Also, kind of a side question. I have noticed some lasers simply have a red dot to mark the center point and other laser engravers outline an entire red box of the area being engraved, etc. What type of option is that?
Any help would be appreciated.
Thanks!
