Jim,

Check out http://www.shopbottools.com/LabFiles/bradyvac.htm . I used this to generate my file . I created a plenum with a grid about 1.25" squares to distribute vacuum readily . The file that comes with the bot it much to course I think but will also work . I created one file and ran it 4 times for 4 zones using the following Shopbot file :

'Start of master file Part File to ceate 4 grids from brady vac files

M2, 48.5,.5
