Hello Pam
That looks like the type of PCB im machining, that means it looks very good . I don't know if the CamBam or the Gcode format is compatible but I would be happy to give it a try, I'm using EMC2 and PyCAM running on Linux. Usually I draw directly in a DXF file the tool path (Its a bit nuts but I got used to doing it this way) and then generate the Gcode. For this one I'm missing the correct dimensions, how did you get the dimensions?
This is a video of a test cut:
