CNC Stomp Pad 6 | CNC Plasma Cutting Video Tutorial | CNC
Last video we checked our g-code to make sure our program was correct. Now we go out to the shop and do some work. We zero out the CNC Plasma Cutter and start cutting our aluminum stomp pad. Once we are done, we look it over and note the slag or dross we will have to grind off next.

CNC to Art Video 10 – Mach 3 G-Code Verify – CNC …
CNC to Art Video Series Video 10:
This is the CNC Video series on how to take an image to a CNC File. This process is one that many CNC Users want to know, but there is not much info on. Here is your chance to get the inside scoop.
For more information, please go to: http://www.cncinformation.com
Before we head out to the shop and begin CNC Plasma Cutting, we will check out our G-Code program in Mach 3. This will give us some confidence when running our CNC Program.
Mach 3 is a great CNC Control Program. It takes our G-Code and converts it into Signal for the CNC Controller. The CNC Controller then sends the signals out to either Servo Motors or Stepper Motors. These motors then move the axis to create motion.

CNC Music Factory – MIDI to gcode
I’m making a note here – *huge success*
First output from ‘mid2cnc.py’, a program to convert MIDI to gcode linear moves, allowing one to play music on a CNC machine (will publish it when it’s done!). The music is Jonathan Coulton’s “Still Alive” from the ending credits of Portal.
Basically, it’s possible to compute a combination of (distance, feedrate) that will cause the stepper motor to spin at an exact frequency corresponding to a musical note. With a little vector magic, the same can be done for (x, y, z, feedrate) to produce chords as the machine follows a 3D line through space.
TODO:
Handle more than 3 notes played at a time (drop some if there are not as many axes…)
Lock notes to their initial axis for their duration (maybe only an issue on my ghetto machine where the axis motors sound very different)
(try to) Improve frequency accuracy where 2 or more notes are played simultaneously (may be a CNC software issue)
A description of how it works is on my blog at http://tim.cexx.org/?p=633

CNC Stomp Pad 5 – Mach 3 G-Code – Learn CNC Plasma Cutting
In this video we go through Mach 3 to look over the g-code. We are checking to see if we have any problems before we go to the CNC Plasma Cutter.

Homemade DIY 3-Axis CNC Router cutting Harley Davidson sign
Quick tour around the machine while it is cutting out a Harley Davidson sign. Some screens shots of the software we wrote to run the controller board we designed. Import files from SignLab and preview on-screen before sending to CNC Router. No need to write g-code. More than one machine can be connected on the network. Each machine is stand alone and does not tie up PC while cutting. Work on another job file and send to a machine that is not busy. Finished sign is shown at the end. Please enjoy this video while listening to Freddie Mercury of QUEEN. Any comment would be great appreciated. Thanks

Home Engineered 3 Axis CNC Router Machine
Home engineered CNC mahine cutting a 3D sign from polystyene foam material. The controller is only 6″ by 6″, and controls all functions standalone after file is sent. Vacuum table holds work material, and a small laminate cutter with 4 flute 1/4″ end mill cuts. Software allows you to load and view design before routing begins. Better than 0.001″ accuracy. Estimated work time. Emergency Stop button. Removeable job cartridge for commonly cut files. Power supplied by 24V 50VA power transformer. Controlled AC for Shop vac and router. Will cut wood as well.

CNC Basics E-Course 3 | CAD | Learn CAD Video | CAD/CAM Tips
In this CNC Basics Video we go over CAD. CAD Stands for Computer Aided Design. During the CAD step we take our initial design and translate it into the computer. We do this CNC Step so we can change the design, resize it, save it, transfer it to someone else, etc. Recording our CNC Design into CAD gives us flexibility.
During CAD we learn we first design parts, then assemblies, then groups, then machines. We also learn there are different types of CAD Software. 2D, 2.5D and 3D. These types also come in different software packages from inexpensive to expensive. You can spend up to the sky if you want.
The trick is to match the CAD Software Capabilites with your CNC Needs. You don’t need high power 3D Modeling CAD if you make simple parts day in and day out.
Tomorrow’s lesson is CAM. Computer Aided Manufacturing.

CNC Basics E-Course 4 | CAM | Learn CAM Video | CAD/CAM …
Here on the 4th day we talk about CAM. CAM stands for Computer Aided Manufacturing. During the CAM step of the CNC Process we use software to define how our CNC Machine should move.
There are a number of CAM Software packages on the market. They range from the inexpensive to expensive. Much of the cost depends on the number of Axis’s that the CAM Software has.
With the CAM Software we define things like stock, location, tooling, feed and speeds and the post processor we will use.
The post processor is very specific to our CNC Machine. It outputs g-code. We use the G-Code program in our control software next.
Tomorrow’s Lesson is CNC Control.
