Latest Edgelit.
Material 3/8 Extruded Acrylic (Cast is next)
Engraved with 60° Diamond Drag Bit.
.002 stepover with .2 DOC at 150 IPM
The lighting is temporary as this is my test rig set up in my shop. This will have a base made with a USB cord to power off of any computer or wall adapter.
Still need to cut the border line on the band saw sand and flame polish the edges.
And best of all I remembered to mirror the image the
second time.

Nice job Dwayne, I've yet to try engraving on acrylic. More information on your settings would be appreciated.

All of my settings have been derived from Dougs (XxRay) posts. In one of his posts I read that he had tested through quite a few DOC settings and it seemed to come down to 0.200 being the optimal setting.
The attached clip is from my particular Drag Bit setup. Up to this point it has been quite a bit of trial & Error. I can tell you from experience Acrylic is definitely the way to go. Several I tried in Lexan just looked nasty and are a bear to clean up.
I will keep posting as I start doing some depth cut edgelits. I just really like the looks of them.
Scovell,
Thank you.
My test rig lighting is actually an emergency exit sign that I hacked to use as a bench test rig for edgelits. Just haven't gotten around to hacking the chip to turn the led's back to white.

Martin,
Least you have put the lexan to one side
Yes I finally did. Took the advice of a friend who gave me a little nudge in the right direction.

Hey you spelled Chicago wrong !
Joking, looks like a nice clean cut, sometimes fills can leave streaks but yours looks nice.

DOC settings and it seemed to come down to 0.200 being the optimal setting.
Yet, in your image the "depth / pressure setting" is 0.006. Quite a difference. The "safe z" is 0.2 though. Are you using DOC to mean "depth of cut"?

I ran a test using different pressures/depth of cut with a drag tool on cast acrylic. It was difficult to see any difference between the different values.
I believe the difference in appearance of the bottom row is because that is closest to the edge lighting LEDs.
