[Cura removes part of my file]

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

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

printer is a geetech pro i3; a prusa clone

 

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