50W CO2 on Granite

I’m thinking about trying black granite or marble to etch a memorial for my mother who recently passed away. I’ve got a 50W CO2 (chinese blue box) laser that performs very well.

Anyone have first-hand experience and any tips.

Use a high speed and low power.You will need to play around to dial it in for your machine but good results are possible. I did these this with a 100 watt and a 2,5 inch FL lens
