Please help,
suddenly the top and bottom surfaces are printed with just 1 layer wall even when I setup it for more. I am sure I tick-off the option “Only one wall on top surfaces” and “only one wall on first layer”, I also setup the “Top shell thickness” and “Bottom shell thickness” to 0. The slicer shows it correctly but 3D printer prints it with just 1 wall. The very fist layer is OK, any other bottom surface (on supports) is 1 layer only. At the same time it started to be impossible to print any slighter overhang- it will start bumping. Side walls are still great.
