As for engraving, I am looking to scribe a very thin line, as in .00025"
I don't think a router will get me that.


I am worried about your choice of material. Styrene is not going to be an
exact thickness so trying to hold that kind of accuracy is not going to
happen. Also if you try and do it with a laser, you are going to get some
heat deformation.

What exactly are you trying to make?
