What's the steps ?

[SScnc]

Well at least you found the problem, I just posted on that. I also have watched some of your vids on YouTube, very good, and your lighted acrylic projects turned out great ! I'm very impressed that you go to the extra effort of providing ALL the specs such as material, endmills used, DOC, feed rates, ETC. That is a real help and very few do that and it's important.

I've done one small lighted acrylic on my X2 and I'm real happy with how that came out, I used a small blue LED strip that came out of a dead XM receiver. Can you tell me what LED strips you used or did you make them ?

Great work and I look forward to seeing more, I'll post a vid of my machine making the plaque in this thread.

BTW: re: your LED light PCB's, I use Eagle and PCB-Gcode too.

Yes, I milled them using Eagle and PCB-Gcode. The circuits are simple series/parallel circuits. If you want some of the eagle files I'd be happy to post them. I settled on 8 inches for the width of my signs. Did you see the wooden boxes?

This is my favorite sign and the last one I made.

I like it a lot too. I have spent the last hour or so looking for a drawing or photo of that dragon. It looks very familiar to me but all the ones I found are similar but not the same one. Can you provide a link to the image of the dragon? Did you carve it as a lithophane or a relief? Post 25 refers to U tube videos with cutting information, can you provide a link to those also? I looked through your posts here and found your blog page and didn't see any links. Sorry if I missed them.

I do really like the way that dragon looks.

The dragon I got from cnc4free.org homepage. Danny was nice enough to repost it for me to use. There is a threads called share your 3d part or art he regularly posts to. I cut it as a relief on the back so the front is smooth.

My youtubes are here

Thanks for the info. I knew I had seen that dragon somewhere. It is no longer on the cnc4free site, I had looked there, but I found a picture in the thread on the zone. I will see what I can do with it.

You have some neat and interesting projects. I am going to check out your circuit boards for the led edge lighting.

I like that too, excellent job!

I missed that. Where's that at ?

Each circuit depends on the number of LEDs (I use 8 mostly) the forward voltage (3.2 for White, 2.97 for Blue, and 1.4 for Red typically). Like I said, I use the simple series parallel circuit designer.

If you use Eagle Lite then for 8" you have to break it into two circuit boards.

jay c,
now your dragon you used a 3d bit and just carved the back side of it?

thanks kevin

There are three tool paths:
1. A cut out tool path with a .125" (1/8") flat end mill and a finishing pass at full depth
2. Relief toolpath with a .125" (1/8") flat end mill roughing with an offset of .008"
3. .0625" (1/16") ball end mill finish with 0 off set and with raster angle set perpendicular to the roughing pass.

I used 25-33ipm due to limitations of my machine. My speed was 11KRPM at a depth of cut no bigger than 1/D of the tool used per pass on the first two paths. On the third, I let it cut full depth.
