My usual settings for my 60w are 1 pass, 12 power, 400 speed for powder coat.
I lased a customers black painted 30 oz Ozark Cup using the same settings and it takes 4 passes!
The main problem which required 2 more passes was an increase in paint thickness at the bottom of the "E"
At any rate, it turned out alright, but if anyone has a suggestion as to proper settings, I would like to know.
