# current code is something like this : https://github.com/ErikZalm/Marlin/blob/Marlin_v1/Marlin/Marlin.pde#L1542
# that is :

void prepare_move(destination){
    limit destination if it's over limits
    feed_line_to_planner(destination);
    current position = destination
}

# we want it like this : 

void prepare_move(destination){
    limit destination if it's over limits

    distance to travel = destination - current position
    number of segments = distance to travel / segments per mm
    temp_target = current position
    for each segment {
         temp target += segments per mm
         feed_line_to_planner(CONVERT FOR SCISORS(temp target))
    }
    feed_line_to_planner(CONVERT FOR SCISORS(destination))

    current position = destination
}

# of course we want the segment cutting thing to be done for Z only, did not add that here for conciseness.
# here is the place in smoothie where that is done : https://github.com/arthurwolf/Smoothie/blob/edge/src/modules/robot/Robot.cpp#L179
