Following the most recent CNC Class, which I think was a great success on many levels, I was inspired to make a project that has been on the back burner for awhile. I want to use a CNC to make some furniture. I’ve been inspired by the work of Gregg Fleishman, and as a starting point I cutout a scale model of one of his designs.

Learn how to use a CNC router to cut 2D and 3D objects out of a variety of materials. TC Maker has 3 CNC routers available at the Hack Factory, come and learn how to use them and start making your own awesome stuff!
The class will have two parts (Machine Check-out, and CAM gcode creation) with the machine introduction and check-out scheduled for 1pm – 5pm Saturday and the CAM workshop from 10am – 2pm on Sunday.
Intro to CNC Class Sign up here. It’s $45 for the 2 days of class

Learn how to use a CNC router to cut 2D and 3D objects out of a variety of materials.
The classes will be held on February 2nd and 3rd. CNC Introduction and Check-out on Saturday, and CAM / gcode creation on Sunday. The schedule will be 10am – 4pm both days. Intro to CNC Class Sign up here. It’s $25 per class / day or $40 for both classes.
VERY IMPORTANT! if you want to be able to generate your own gcode (so you can cut out something you want) you will need to take both classes, The CNC introduction class is just to demonstrate safe and proficient use of the machines, and everyone will be cutting a pre-selected file that I have prepared. To cut your own creations you will need to take both classes,
Intro to CNC, CNC overview and safe use check-out
Attendees will be provided a 2D gcode file, and need to demonstrate proficiency, by safely cutting the part on the machine.
Intro to CAM, 2D and 3D Computer Aided Machining (CAM)
Attendees will be given an overview on how to use 2D and 3D CAM software to generate the gcode or tools paths that the CNC machines use to cutout parts. Please see the important notice below on how to acquire the software before class so you are ready to go!

I’ve been wanting to try this for sometime, and finally had my setup mostly ready and the right materials. A Lithophane is an image etched into something translucent. In my case I used LinuxCNC, which runs my CNC router, and includes a script called Image-to-gcode, that creates a gcode height map based on the color or light to dark variations in an image. The material I used is 1/2″ Corian.
The original picture is this one of my son at the beach.

Carving a skateboard mold prototype in foam. The mold itself will be made of laminated lumber to support the pressing process. This test was to determine what bit and step over (the overlap of each pass of the bit) would achieve sufficient detail, and not require too much finish sanding. The process and pattern for finishing is like an ink jet printer, but it cuts each pixel in 3D.
It may not be readily apparent in the photos of the carving, but the board has pretty complex compound curves. I’ll include a shot of the model which illustrates this better after the break.This is a shot of the roughing pass being completed. The test chunk is about a 1/3 of the skateboard’s total length, and the foam was a bit undersized so the board is a bit wider than what the foam could capture.

We’ve been making progress on the Global Hacker Space Challenge components. There are lots of activities going on, on different aspects of the project, and we are exploring multiple methods to create many of the parts. This is an image of a test cut for the positives of some 10xed 3mm LEDs.
The video is of a cut that went not so well of a 10x ATMega chip. I had neglected to restore my backlash compensation settings after making some updates, and the Z-axis lost height through out the cut making a sloped chip, and turning chunks of my spoil board into fine powder.

Jim Hart, Boltz in the forums, made me some 1/4″ aluminum plates for my CNC Router. The plates work perfectly.
