I forgot to mention that the US Digital MA3 magnetic shaft encoder is not required. You can use the PWM from the X-Carve’s grbl instead with the Flexmod P3 laser driver to vary the intensity of the 6W Laser Diode. Our Shapeoko 2 is setup to use either of the modulation control methods.

I don’t think I am quite set up to create the air assist detail but it was good for you to share. Awesome!

Another 6W laser diode 3D engraving example done in Poplar. Two separate gcode files were generate with PicEngrave Pro 5 from the same depth map image. One with X,Y & Z commands and another with X,Y,S & F commands. The two gcodes files were then combined together to create a new file with X,Y,Z,S & F commands on every line using our PicLaser 3D. The purpose of this was so the laser’s focal point would follow down into the darker, deeper cutting areas by having the Z axis moves in the file.
We developed PicLaser 3D for carving a 3D spindle relief and then Laser engraving shades on it afterwards. When the gcode is combined in this manner, the laser’s focal point with follow the 3D spindle reliefs profile to maintain the focal point on the surface.
This is the first time trying it by just using a laser diode for both of the 3D engraving processes done in one pass. More experimenting with the settings is surly needed.
This was a small gcode file with only 715,035 lines of code and of course, we used PicSender to stream it to the J-Tech PWM grbl. It was 5"W X 7"H in size and it took 5:00:19 in time to engrave.

Another 3D laser engraving example done on Poplar with our 6W LD. Analog modulation was used from a US Digital MA3 magnetic shaft encoder using X,Y,Z & F commands and grbl 9J. The size is 5" X 5" and it took 1:27:44 in time to engrave.

anyone do anything on plexglass?
Our PicEngrave Pro 5 interprets photos/images into gcode depths of cuts or laser power values. You need a Depth Map image for cutting a 3D relief with a spindle, or a 3D laser engraving.
It will generate a gcode from a color or grayscale photo to cut a Lithophane or photo engraving in wood too.
From our web site:

* LazerBlade PWM Gcode Support
* Mach3 TTL M10/M11 Gcode Support
* Advanced Gray Curve Adjustment to Lighten Mid-Range Shades in an Image
* Auto calculation of engraving size based on Pixel Resolution used
in the "Edit Image" Auxillary Program
* 3D Printer controller support for the J-Tech Laser systems.
* Save and Open Profile Settings for Different CNC Machines and Materials.
Note: We highly recommended to use PicSender for streaming these very large,
fast changing Raster Gcode files when using Arduino UNO and EmBlaser
(aka LazerBlade) and Other GRBL Controllers.
It does not give the option to set a tool. The gcode is optimized for a fine point V-bit when using a spindle.
You can download the Demo for testing and it will add watermarks in the image until registered. Yes it’s $90 and our PicSender streamer is sold separately. It’s not required, but is recommended.
Thanks.
