Okay. Now I have tried several parts and printing them with the settings present here, https://www.737diysim.com/build-guides-1/boeing-737-throttle-quadrant-v3 Usually it ends up strange.This is my spoiler handle, full of squares, and not a solid backside.So I think something must be wrong in general settings I have.This is the nice side where the printer ends its job = the top layerAnd this is the side closest to the bed,Not a pretty sight and useless part according to me. This is too basic look to use.This time I have set support to lines like this,So what to do?I chose to have 100% filling for stability. But why this strange pattern and bad lower side?It does not seem solid with all the thin lines visible.0.2 resolution can never, ever give the smoothness of the parts you can see in his videos. That is impossible.So does anyone have a good suggestion what might be wrong here?
