Autobed levelling issues

Hi all,
I tried to set the autobed levelling features on my 3d printer under marlin, with a servo and a probe attached to it.
I have some hard time getting it to work
I have several issues:
1 - Probing done well, but Z axis is not adjusted when x or y moves ats it should.
I changed G90 for G91 in my start gcode in cura, then Z is adjusted during the print but pronterface can't read the gcode file properly.

2- Sometimes it just pretend to probe but doesnt go low enough to trigg the probe, it just raises like it was triggered but 5 mm before...

3-The servo raises and lowers the probe between each touch, and before z is raised, resulting in the probe bumping into the bed.


I have the feeling that cura and pronterface add, some kind of gcode before yours like some g28, adding some problems sometime...
I will be greatfull for anyhelp,
And... It's frieday, so have a nice week end!

4.3.6 G91: Set to Relative Positioning
4.3.7 G92: Set Position

would you want to change g28 and g29 comands?

4.2.3 G28: Move to Origin (Home)
4.2.4 G29: Detailed Z-Probe
