Are you sure that the acceleration you have specified is the maximum your machine can do? On the (teeny) machine I have the most experience with, the acceleration time, (maxvel) / (maxaccel), is 0.017 seconds. On your machine, (maxvel) / (maxaccel) is .24 seconds. As a gross simplification, the trajectory planner enters "pathological" territory when the time for a move is less than the time to accelerate from a stop to the feed rate.
In emc 2.1.0, "G64 P-" (continuous mode with path tolerance) mode will combine multiple G1 moves into a single motion when they are within a tolerance value of a single straight line. It is hoped that this mode will do better with CAM output like the code you seem to be dealing with. This mode is most effective with code that contains only G1 moves (no arcs), because it will never combine a G1 with a G2 or G3. If neither of these help, then it sounds like your best bet is to have your CAM software create output *with* arcs, since you get up to 6500mm/min that way.
