Posted · Elephant foot in Cura slicer, please help?

Hello! First time posting here. I've used Cura ever since I got my printer, and I've never looked back :)

 

I'm having an issue, and I'm not sure how to fix it. The first layers of my solids are being sliced in a way that I get an "elephant foot". Note that I don't mean I'm getting an elephan foot in my actual print, I know how that can be fixed with some tinkering; I mean the first layer in the slicer is made wider. I'm attaching a picture of a sliced solid to show what I mean. A wall that should be vertical from bottom to top is wider in the first layer.

 

Is this expected behavior? If it is, is there a way to disable it? I made sure that the first layer height is the same as the rest of the print, and that the first layer thickness is 100%.

Any help is appreciated!

    My first thought was also that you have "initial layer horizontal expansion" set to something greater than zero.  I usually set that to a *negative* value to get rid of elephants foot.  Setting it to a positive value will just make the foot worse.

    Regarding the "initial layer horizontal expansion", it's set to 0. I could "fix" this problem by setting this setting to -0.1, but I'm guessing something must be wrong elsewhere in other setting.

    I'm attaching my project file in case anyone can take a look. Any help is appreciated!

    You have set the initial layer flow to 150%

    When set to 100% it looks like this

    Oh, yes I did set that to 150. Guess I forgot about it, thank you so much!
