am buying a new dual head router and need to tie the two heads together. i can do this with g61zw and this will move the two heads on the axis as a single head. what i cant figure out in mastercam (v5 router level 1) is how to set up each head with tools and figure out how to offset one head from the other. i need to set the heads up 24" on center. when i do a test file and try to post it, it says there is a negative number for the tool on the second head and posting will stop. i have not received the machine yet, just trying to learn mastercam before it arrives. am a complete newbie to mastercam, however i can draw the parts in 2d, toolpath, and then nest the parts. just cant get the dual head part working. thanks for any help.
