You showed the "prepare" view.  Please show the "preview" view after slicing that part.

 

I suspect the problem is more with the printer than cura but I need to see "preview" mode to be sure.

Thank you this is the preview

 

printer is a geetech pro i3; a prusa clone

 

the extruder goes straight ahead at the  place of the "spikes"

So you can see clearly in the preview that Cura is printing those bumps.  Something is off on your printer.  I'm guessing that your first layer isn't sticking very well.

 

It would be helpful to show the first layer of your print complete (and failing).

 

Here is a video that explains well how to get the first layer to stick - VERY VERY WELL:

No, because at the first layer the printer does a straight line instead of moving and print the bump. If the first layer isn't ok, the extractor will does the movement to make the form of the bump, but it does a straight line a the postion of the bump. 

 

the anorther  outlines of the piece are good and with good sizes 

 

thank you

Ok thank you, i've understand something, 

 

I don't know why but i think that the end stop of the plate have moved. I've turned the piece with 90° angle, and the piece is good.

 

After test I discovered that the end stop have moved, so printer's plate stop and don't print the bump

 

thank you for your help
