300 mW! Laser Diode.

There is an image to Gcode program that can be used to raster engrave a photo for using on an Arduino with the GRBL Gcode interpreter Contraptor.

Here is my dust boot I made for my CNC router. Yea, it's a Mr. Gasket cast aluminum Small block Chevy thermostat housing. Picture does not show the brush that will snap to the bottom of it, but most...

It sure can be done, with a little imagination. It requires a spring loaded diamond tip bit in the spindle.

Photos could be done this way on the...

Dan,

I do appreciate the compliment of your comparison of my 445nm LD build to a Ferrari, considering Ferrari's are mostly hand built too, but why do you have to insult Arjen with comparing his...

Thanks Arjen,

It has been allot of fun with these builds. I like figuring out multitasking ways to use my CNC router. I have even thought about a 3D printer attachment to go on it in the future. I...

Actually Arjen, the 445nm whitened the black anodizing with high power and at lower power it stays black. The servo motor down below (4th axis) drives a US Digital MA3 magnetic shaft encoder. It...

We are using two 2.25W 9mm Nichia LD's focused to the same intersecting focal point and it's mounted on our servo CNC router. The Nichia 9mm LD came from DTR on eBay for $99 each already pressed into...

Thanks Arjen,

We built and installed the 445nm LD engraving systems on two of our CNC routers. Both are 4 axis machines.

Yes, I have used a 445nm on anodized aluminum. I had to go real slow with 4.5W of power.

That is what we are able to do with our CNC router. The Z axis goes up and down to follow the contours of the 3D spindle engraving to maintain the laser diodes focal point on the surface of the...

That would be reinventing our wheel. We can actually 3D spindle engrave a relief in wood and then laser engrave a photo onto it with shades afterwards with the same machine. :)

Please count me in.

There is a free download program called Blender that is capable of generating these type of greyscale images. There are Bas-relief downloads available on different web sites. These type of depth map...

Add my name. Thanks.

Dave,

This is what I determined. The Range switch for changing it from 1W-3W-10W-100W is flaky. When we did this test before (months ago) we set the range to 3 for the 1W diode and it read 1W....

Hi Dave,

The Diodes we are using is a 1.6W Nichia NDB7875, but we are pushing them with higher amps then the max ratings. A good heat sink is key when doing this. Max amps on these are 1.7 and we...

Thanks Dave,

I have done another test with my Coherent brand laser power meter in the past where I de-focused the beams slightly and shot them at the thermopile sensor and got a reading of 10W...

Wasn't there lyrics LSD induced and why they were considered an Acid Rock Band? I believe they were referring to an Acid trip when they sung those lyrics. I'm curious, why would that be your favorite...

Thanks Dan,


The lens that we are using is the best that is available (cost wise) that gives us a small enough spot for our analog modulation line engravings. I'm happy with the results we are...

Very good job John!







Dave,

Dave,

Tweakie has never done anything like what we have with laser diodes, that I'm aware of.

Jeff

Thanks John.

Dave, what John said. :)

Dave,

There is no cube to combine the beams. Both diodes are mounted at a slight angle in a V configuration so the two beams intersect each other at the same focal point. Here is a picture of one...
