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 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 1 – CNC Project Introduction – Learn CNC Cutting
CNC Project that is shot in a tutorial sequence. It goes from the Design, CAD, CAM, Control, CNC Plasma Cutting and then final assembly. Check out this CNC How-To.

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.

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.
