Hello, and Happy New Year! I am new to the engraving world and need urgent support with figuring out what parameters/ settings work with this material. 

Please help! I offered to engrave 100 of these champagne Flutes (50 white/ 50 gray - not sure if the color matters) for my sister-in-law's wedding reception this Saturday, January 11th. I think I bit off more than I can chew, I didn't think finding the correct settings would be this difficult. 

Please save me and the reception! I and very grateful for any support that comes my way! 

Thank you in advance!
