is there a way you can set bobcad to generate absolute IJ ? would that fix it ?
Also, what are IJ exactly ? how do they work ? I notice and understand the x y and z.. but what do i and j have to do with anything ?
sorry, realllll newbie... 
Thanks !

To add to what Gandalf said. Have you tried to setup BCC to Program using "R" instead of I and J?
Also I, J, K are relative to X(I) Y(J) Z(K) respectively.
