Modifying PostScript code to generate outlines for laser cutting tCream layer from eagle
This was my frist attempt at acutally modifying postscript code, and it worked. The tCream layer outputed from CadSoft eagle’s CAM generator (PS) will generate a number of filled in boxes. I modifyied a function inside the postscript file to generate outlines to be used with a laser cutter. You need to save the file as a PS file, open it with a text editor, and replace the /b function with this one..
/b { % draw a bar
/an exch def
/y2 exch def
/x2 exch def
/y1 exch def
/x1 exch def
/w2 x2 x1 sub 2 div EU def
/h2 y2 y1 sub 2 div EU def
gsave
x1 x2 add 2 div EU y1 y2 add 2 div EU translate

I’m not sure if it’ll help anyone else out there, but it works for me
