In the full settings, what the is difference in the bottom/top thickness setting on the basic tab and the initial layer thickness setting on the advanced tab? Isn't the initial layer the bottom layer?

    Initial layer thickness overrides your layer height thickness for the first layer - say your layer height thickness is 0.1 but your initial layer thickness is 0.3 then the base layer is put down with a bit more splodge to get it to stick well.

    Bottom layer thickness and top layer thickness are the number of layers put down before you get to your 'fill' variable - and this is important. Let's say you use 10% infill - it is obvious with your .1 layer height there would barely be any material covering over the top of your infill matrix.

    So if you want 10 layers at the bottom of your part - then with the .3 setting it will put a first layer of your bottom layer down a bit thicker to hold the part, and then complete the 7 other layers to give you 1mm (I think that it right and that the base layer would not be 1.2mm but don't know that for sure.)

    Hope that is clearer :)

    Actually, no... it should give you 0.3 + (7 x 0.1), I agree, but it doesn't. The number of solid layers on the bottom doesn't take into account the first layer thickness. So you get 0.3 + (9 x 0.1) instead.

    Well, actually, no, you get 0.3 + (10 x 0.1) because there's another bug that you always seem to get one more top/bottom layer than you should.

    I filed a bug report against CuraEngine for both these things a few days ago.

    OK illuminarti, let me see if I've got this straight...So for now, my actual bottom thickness will be the bottom/top thickness setting + whatever my initial layer setting is.
