The images you've posted show a layer height of 0.4 mm and a nozzle diameter of 0.8 mm. These are unusual numbers unless you've modified your printer or it is configured for large high speed printing. I found on their web page that one can purchase the larger nozzles. Confirm the nozzle diameter you have and change the settings accordingly. You should not have a layer height more than seventy five percent of the nozzle diameter. For a 0.4 mm nozzle, the most common size, 0.3 would be the max layer height.

If your nozzle is indeed 0.8 mm, the 0.4 mm layer height is acceptable.

Check your nozzle and report back.
