Looks great! Do you have a link for the 2 types of mirror?
Thanks. I had rushed through the article and didn't catch it.
That's a very nice looking shelf unit. Did you use any particular kind of knot when tying the cord around the joints?
I'm very, very interested in this. I've been looking into building a light duty cnc machine for sign carving and laser engraving, and this looks great. Since I'm new to all this, I have a couple of questions:1. Does the carving/engraving pattern come from vector images, or from raster images. I've read that using vectors causes the cnc to rout or engrave only the outline of images. I want to cut images like the attachment into wood: So, I would need for the router to cut out all of the dark areas, not just the outlines of them.2. Do you think the framework of your unit would be strong enough to be able to use a trim router, or even a full size router without any shaking or wobbling? I really like this, and I voted for it!
Great information. I'll get busy on the BOM. Thanks.
I like your project. I like that you have included info for routing, engraving, and 3d printing. I have one question: In your demo, the pen is moving extremely slowly. Could the movement be sped up considerably when routing? Thanks.
Yes, it does. You've been a great help to me, Marc. I'll start looking now. Thanks.
More good info. Thanks for taking the time to help.
Thanks, Geordie. That's what I wasn't quite getting. So I'll be able to do what I'm planning. I don't know if you saw the example I was showing in the instructable comments. It's a portrait I router carved, and am wondering what wattage laser module or tube I can use for only doing that. It will be in soft wood, and only about 3/32" to 1/8". Thanks a lot for your help. Jim
Wow! Thanks for this thorough and detailed explanation (you told me what I wanted to hear)! And thanks for the example photo. I forgot to mention in my question that I will be engraving in soft wood, like cedar, pine, and fir. The deepest I would need to go would be 3/32", 1/8" max. What wattage module could I use for that depth? Again, thanks a million for your help. Jim
Great advice, Geordie. The same for your Tips and Tricks article. I'm just starting to consider using laser etching on wood, and not quite grasping the line width capabilities of laser etching. I will be mainly doing vectorized portraits, and up to now I've been routing them with a trim router loaded with a 12 degree carving bit. I need to know if a laser engraves various widths (according to the vector you're copying) by making more passes until it fills out a wider area in some parts of the image. For example, for the carved image I'm including, would the wider lines ( like the throat and mouth area) be done, or just a thin line for each part ( like the whiskers)? The image is about 6 inches high, and 4 inches wide. Thanks for your help.
It doesn't matter how old you are. This is a real achievement. Congratulations. I have a question. I noticed that you had engraved a design on a couple of wooden keychains. Have you experimented with how deep you can engrave into the wood (for example, 1/16 inch) ? Thanks.
