Posted · Cura not allowing more than 3 bottom layers

Using Cura v5.2.1, and I have "Layer Height" set to 0.2mm and "Bottom Thickness" set to 1.0mm.  Cura correctly calculates that I should have 5 "Bottom Layers".  However, when I slice it, only 3 bottom layers are laid down before my infill starts.  This doesn't happen with the top, where there are correctly 5 Top Layers put down.  The "Bottom Layers" says it can be affected by the following settings and i've included what I have them set to...  not seeing why my solid bottom layers (lines) is stopping after the 3rd layer...help!? 🙂

  1. Bottom Thickness = 1.0mm
  2. Spiralize Outer Coutour = off
  3. Infill Density = 20%
  4. Layer Height = 0.2mm

    Looks like the issue is a different setting overriding that value.

    Your "initial bottom layers" is set to 3, this is why you see that result.


    The setting you adjusted is any bottom layers not touching the build surface.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
