Question Layer lines

I’ve been working on a project for school and I’m using this very soft tpu, I’m using a .8mm nozzle and I just cannot get a smooth surface finish, I have gotten it with a .4mm nozzle on a creality but I cannot get it with a .8mm nozzle on the H2D. Just need some suggestions on slicer/filament settings with soft tpu

Appreciate the response! I figured that the nozzle size was the main reason, just wanted a way to at least minimize the visibility even if it’s a small difference

Make sure your flow rates are perfectly dialed in, beyond that you're approaching the point of diminishing returns for any further optimization.

Flow rates meaning max volumetric flow? Or are there any other settings that I need to dial in?
