Greetings! Long time no see!

Say, I am etching a bunch of those typical tapered bar glasses (generally filled with beer). I am looking for a good way to engrave it. I have a 50W Epilog Legend with the rotory attachment. I am using black and white in the corel file for the engraving. I would like to know if you have any tips or speed/power/RESOLUTION suggestions for doing this sorta thing. It's my first go.

I use 70% black at a setting of 500dpi, 95% power and 12 % speed Trotec 25 (87in/sec =100%) Position glass so the entire surface to be engraved is in focus (parallel) with laser (raise the lower end of glass) I have center positioning Rotary not a barrel roller....Since the barrel of the glass is tapered. the circumfrence in getting smaller at the base. find a mid point for measuring diameter/circumference and position Logo/text in the middle/center of measuement.
