I really wanted to make a few drawing on the CNC router (Shopbot Buddy). I did a few experiments using different techniques and mediums.
I started using simply pen and paper, then refined that technique using a pen with a spring attached, later tried over canvas and finally using different markers. It was a fun and quick project and the best of all you then can hang your art in your home or office.
Here is a preview of my experiments:
Selecting your artwork: I wanted to make a small set of drawings so I selected a really nice set of line drawings of motorcycles. You can check them out over here: Photos: Some Classic Motorcycle Line Art Drawings
I used LiveTrace from Illustrator to vectorize the image but if you have a vector drawing already, much better.
Canvas: I found these canvas panels: Art Alternatives Canvas Panel - PACK OF 12 that were really economic and good for my paintings. They are really easy to stick to the worktable of the CNC Router. I taped the for edges and stayed really firm.
