I tried printing a design that needs a smooth top surface but I can’t get it to come out smooth. I get this weird pattern and I cant find a solution.

i print with a 0.4 mm nozzle at 220° and 0.2 mm layer height using poly terra pla ( I dried in a filament dryer ) and I have ironing on. I print using the bbl a1 mini and use Bambu studio for slicing.

thanks in advance!
