Can the acceleration be changed dynamically through HAL and still work properly? Because say the traj planner looks 10 moves ahead, and it's 2x G1 followed by 3x G0 moves then 5x G1. It forms a plan based on the acceleration rules. But when it hits the 3rd command, the HAL suddenly changes

Hmm, interesting, but that's only to reduce accel in manual mode, right? It'd reduce shaking while using the mpg, but the G0 moves in the g-code would create motor stalls if used at full speed. I'm wondering if all G0 and manual input could be a mode of higher speed but more limited in
