So I tested the standard speed the sport speed and the ludicrous speed. As you can see there are different shades of the gray. The lowest level was standard I then changed to ludicrous then to sport. Then directly under the logo it slowed down on its own to do the color changes. So why the different shades of gray?
It’s because of the different speeds. When you change the speed, you also change the extrusion and thus the temperatures (time the filament is hot and melted + the time for cooldown before the next layer is printed on top).
