I did try to implement a zero look-ahead finite jerk planner for laser rastering. It was interesting, and I learned a bit. It is easier the less general you make it. Ideally LinuxCNC would have a 9-axis finite-jerk planner that handled arbitrary kinematics with feed-override control. Tiny-G is a 3-axis (I think) planner with trivial kinematics and no feed override (AFAIK). At the moment I would be happy just to see LinuxCNC handle more than 3-axis blending. It's in Tormach. I have a feeling that kinematics is not a problem in most cases, the kins functions run fast enough to be used for finite-difference differentiation / numerical integration. I am not sure about the more computationally intensive ones, such as genserkins.
