Why is all that needed? EMC homes each joint separately, disregarding kinematics or anything else. Tom's problem is to home 2 joints on index pulse from a single encoder. As I mentioned, homing is done independently for each joint, so the problem is how to tell EMC to use index pulse from one particular encoder for 2 different joints. Since there are no HAL pins for that, it seems like not possible at the current moment.
