M100
G28 X0 Y0
G29
G92 E0

You also need to add in the heater codes etc. as well.
I don't know what the M100 is for - perhaps the light on top? (Too lazy to look at the source code)

Here is my start code (in Slic3r Printer Settings tab).

I will give it a try.

G21; set mm units
G90; set absolute coordinates
G28 X0 Y0; home X&Y
G29; probe bed
G92 E0; reset extrusion distance
G1 Z5 F5000; lift nozzle

The problem is in your starting G code.  You cannot have G28 after the G29 or it will reset the bed leveling data.

Alright, I put back the G28, but before the G29 and so far it seems to have change my printings. Thanks a lot !

Of course, after doing this, other problems occured, but for now it will do.

The problem is in your starting G code.  You cannot have G28 after the G29 or it will reset the bed leveling data.

After removing the G28 code it does this:
1) when calibrating, it calibrates in midair. This means the probe is moving into those 9 points, but the bed is aproximately 10 cm away.
2) after this "calibration", when it starts printing, its doing it at those centimeters in the air (estimative 10 cm, but I dont believe the exact distance is that important).

Please post the exact code that I should have in the starting Gcode. Thank you !

Hmm, interesting but not sure about this. Havent heard anyone.

Other ideas ?

I've seen the bed vibrate while translating which could cause for incorrect height measurements. I'm considering putting lead weights on the rear ledges of the underside of the bed, but others have used metal springs connecting the bed to the floor or the case.

Also make the bed is even moving as the printer head moves around for a single layer.

This 4 images sums of the problems for me. If anyone has any ideas I am open to sugestions

You may have a loose connector to the extruder motor. Take a close look at the contacts as the printer head passing over the areas you have pictured in the top right. Mine was shorting and caused similar issues. IF there is no short then the leveling is too close as you suspected, not sure how to fix that other than having the probe do it's thing..double check your G-code in this case.

I use 40% and still there are small holes on top. By the way how did you manage to level the bed. Cause mine is giving me the hedache (the probe or the software doesnt take in consideration the fact that the bed is not leveled).

I set it to auto-level the bed at the start of every print. Works fine for me. That's about the only problem I haven't had!

I would suggest maybe upping it to 35 or 40% then, and see if that helps. Obviously, the higher the infill level, the less space there is, meaning that there is more for the top layer to stick to.
