This will help you with many things, including your elephoot

in my opinion the most direct approach to reduce them is smaller first layer height like 0,2 maybe 0,1 mm. But that needs a perfectly levelled bed.

i am working with 0.1 first layer.( on cura)

there is a way on cura that i can change the height between the layers ? ( all of them supposed to be the same )

on a second try i put the fans on 35%

bed on 50C

and increase a little bit the height of the nozzle.

it works better but maybe it be just some Luck

usually, the elephants foot only happens at the very first layer, but yours seems to be several layers high. I can't see it on the pictures. does it go narrow shortly after the first layer and then some layers later a bit wider again? This could be the fans turning on. Maybe set "fan full on at layer" to a higher value and reduce fan speed a bit? But I think you have to live with that effect to some extend. If it is your own model, maybe add a notch to the bottom to compensate for the foot?

If you go to the Advanced tab, under Quality, you can set "Initial Layer Thickness" to whatever you want - i.e. just the first layer. On Basic tab, under Quality, you can set "Layer Height" to whatever you want - this will apply to the 2nd and all subsequent layers. There are a couple of Cura add-ons that let you adjust certain settings at chosen layers but I am not sure if you can adjust the layer height; think not but I could be wrong.

Picking up on @avogra 's point if it is your model then reduce the dimensions of the 1st layer by .1mm (say, you may have to play around to get the exact dim.)
