Thank you all for the nice comments !!

Hi Larry, I'm using  it every day now. I do experimenting with patterns and parameter settings . I try to learn a little bit each time.

Hi Alex, at 85% power and 150 mm speed, it engraves about .025" deep..so it is  a depth engraving to a degree!!

Hi Bruce. Thanks for the tip on the rock engraving and painting. I've not gotten into that yet but these commandments would be nice on two white  rock/ tile/stone tablets, 

Question for you: I have an order for a logo with 3B's tied together in the corners. If I get it built with each of the B's about 4" long, is there a way to treat them as a group so I can take that whole thing and shrink and grow it so they stay in the same relation to each other ?
