Android Mach3 Remote Control

My latest phone is an Android HTC Incredible.  I really love what I can do with it.  I have had it for about 6 weeks and have been dying to write a program for it.  It is programmed in Java and I know Java quite well, so I knew it would not be a big […]

The Age of the Self Replicating Machine.

There is a saying amongst DIY CNC router builders that goes something like this… “You only need to build your first router good enough to build you second one“.  In my case that turned out to be true. I built a wood, conduit and skate bearing Solsylva router.  I painstakingly layed out the various pieces using calipers, t-squares […]


I am just amazed, and I am not easily amazed.  I saw this SketchChair application at the Ponoko Blog.  This is just plain amazing.  I love Flat-pack and this is like Flat-pack crack.  This program is a collaboration between Greg Saul and the JST ERATO Design UI Project in Tokyo.  This is a Processing based […]

Laser Optics 101 – Lenses

The useful power of a laser comes down to power density.  The more power per unit of area (power density) you have, the more cutting power you have.   The beam that comes out of a laser has a rather large diameter.  It is much cheaper to increase power density by focusing the beam to a small […]

D.I.Y. Selective Laser Sintering – Update

Update. Peter is still working on his SLS project.  He is experimenting with a new fully laser-cuttable x/y stage.  He is catching some flack for the ideas in some blog comment sections like hackaday.  Obviously there is some refinement needed for accuracy, backlash, etc, but I applaud his efforts.  I am sure some of his ideas will find […]

Creating A Laser Post Processor

Virtually all CAM systems allow you to target different CNC machines through the use of a Post Processors (post).  Post Processors tailor the ouptut to the target machine.  While most machines can handle G-Code, each machine has it’s own requirements.  Many Post Processors are so flexible that you can even get them to output HPLG, […]

Mach3 Laser Cutter Setup

Many DIY laser builders come from a CNC background.  They have built a CNC mill or router and gained the confidence to try a laser build.  They love Mach3 for the CNC, so they want to use it for their laser cutting.  There are some inherent problems, but in most cases it will work fine for laser […]
