Well you didn't mention the flybar.
The flybar must be tracked, too.
Take the blades off again (you have them marked so you can get them back on right, right?).
Unplug the tail motor noting the polarity very carefully.
Balance the flybar first by loosening the little setscrews at the flybar control frame and measuring very carefully from this point to the weights at the paddles. Slide the whole flybar until the distance is exactly equal and then tighten the setscrews.
Now get each of the paddles exactly parallel to the flybar frame and to each other. Make sure the screw/nut is tight.
Run the main motor up Gently, enough to be able to see if the flybar is wobbling or is out of track. If it is and you can't fix it by this adjustment, then it probably is bent and needs replacing.
When you put it back together be sure the main blades aren't too tight in the grips. They should just barely be tight enough to hold position when the heli is held sideways and given a gentle shake.
Too tight will cause all kinds of problems.
A little wobble of the mast is OK, it should smooth out at RPM, if it doesn't or if the whole heli vibrates, you probably have a bent shaft or severely out-of-balance blades.

At least I think I am understanding you.

when i was standing right over the heli that when the main rotor is turning the head moves about at max 1mm.

but now that i read this phrase again it isn't really clear to me just what the heck you mean.
