I want to engrave lettering into a black with gold undertone acrylic. I want to use 90 V bit. I tried once with .02 depth per pass and depth but the bit when through the material. Should I try .01 or even more shallow than that?

How thick is the material?  
How are you setting zero?  
How are you holding the stock down?
