Andy: The problem arises only when jogging in the negative direction, not in the positive one. I have DEFAULT_ACCELERATION defined, to a value apropriate for the linear axes but too big for the rotary axes, which is why I have to slow down the max speed when jogging in world mode. I have studied that part of the code, and it expects both positive and negative values (it calculates the next position as next position = actual position + velocity * cycle period)
