you check the Image above. I’ve created my own Y+ calculator. So at the Right hand side you can see all the values I’ve use Y+ 200 and according to this My First Layer thickness is 0.010792 and My roughness Height is 0.01 m
So In order to catch the roughness your First Layer thickness has to be twice or thirse bigger than the roughness height. and my ratio is somewhere around 1.0792.
Let me know if you need any additional information.
