Engraving Metal Plaque

Does anyone have a suggestion on settings to engrave a small 2.5 X 1 inch metal (brass I think?) plaque? I have a 100W CamFive laser and am using CerMark LMM6000 prior to engraving. Is LMM14 better for brass? Thank you.

I use Laserbond 100. I have a 100w, and have found that 300mm/sec and 30% gives the best results on my machine for brass and aluminum.

If you have a sample piece of metal, do a speed/power matrix to dial in your settings for the product you useā€¦
