Elephant foot in Cura slicer, please help?

[DavidSL448 0]

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!

Hi, please save the project file and attach to this thread so we can look at the settings you have used. Thanks.

What is the value of the "Initial layer horizontal expansion" ?

[gr5 2,194]

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!
