I am having tons of trouble trying to engrave blue powder coated cups. I have a customer that has brought 2 different cups in for me to engrave and I keep getting the same outcome which makes me wonder if it's my settings. I have a Gravograph LS100 35w laser. The attached picture is 100 power, 35 speed and 300 dpi, 3 passes, wiped down with DA and a magic eraser. I have tried higher DPI with the same power and speed on a different cup but still got a haze and end up "scorching" the metal. Anybody got any suggestions?
Thanks in advance
