Click “Output Format” and select file type: “.gcodes”.Select the test image.png file by clicking the “Input File” button and navigating to the “Test Images” folder.When the program begins do the following to test your setup: If you see a command prompt for a split second and then nothing when you run one of the above then recheck you have all the correct programs installed and the correct version of python (2.6!). (Cad.py) Plotting with Makerbot Unicorn.py -> For use with Makerbot Unicorn system which uses a servo to lift the pen off the page.Commands need to be switched for use with a laser, see “Optimisation” below.) (Use fan port for solenoid as it is switched on off with gcode M106 and M107. (Cad.py) Plotting with solenoid or laser.py ->For use with a 2 axis bot where the pen is lifted of the page by an action such as a solenoid or a cutting action like a laser is required.where the pen is lifted off the page due to the movement of the Z (vertical) axis. (Cad.py) Plotting with Z axis movement.py -> For use with a three axis Cartesian bot such as a reprap, Makerbot etc.I have included three types all with the same interface but each outputs slightly different gcodes. Cad.py and some test images ( SourcForge) scipy-0.10.1-win32-superpack-python2.6.exe ( Scientific Library for Python) PIL-1.1.7.win32-py2.6.exe ( Python Imaging Library)

numpy-1.6.1-win32-superpack-python2.6.exe ( Numerical Python) Note that python 2.6 must be used for cad.py to work. Either un-install newer versions or dirct cad.py to work with python2.6 only. Download the following software for your respective OS.
