Hello Again
I found my mistake (I didn't use the 1.1.8 version of Marlin) all is working just fine ! THANK YOU SO MUCH !!!
Now I work on personnal setting (disabling the home to safe zone (because I use to print high objects) and fine tune the geometry of my printer) but it s excellent !!

Thank you again.
