Making circuit boards on Camm

Step by Step

 * 1)  Decide_what_function_your_circuit_board_should_have
 * 2) Design the circuit board or select and download a cad file from the hello-world circuits section on the http://fab.cba.mit.edu/about/fab/ or from hello world electronics
 * 3) Get copper foil ready in the CAMM machine
 * 4) Open Cad.py software
 * 5) Click input and get the design file (.cad file) or a pre-designed png file.

Make the toolpath

 * 1) Open CAD.py in a Linux Terminal or click on the shortcut launcher in desktop.
 * 2) Make the toolpath for the circuit.
 * 3) Click CAM
 * 4) Click Output format and choose .camm (CAMM)
 * 5) If you're using a circuit board written in Python, you'll find a line near the bottom saying "#dpi = 500 ".
 * 6) Move the ("#") sign to the line above which is "dpi=200
 * 7) * The "#" symbol is a comment, which will ignore the line of the command after the sign.
 * 8) * Use "dpi = 200 # low resolution for previewing" for previewing toolpath contour
 * 9) * Use "dpi = 500 # high resolution for machining" actual rendering and sending to Modela (takes longer to render)
 * 10) Set contours to 1 (meaning 1 outline)
 * 11) Click Contour
 * This will set the toolpath for the file
