@thomasthetrain
I've printed with M579 and this is the result, now the 80 mm is perfect but still not the rest.

thanks for the tip but because the differens in dimentions is not linear i can't apply M579, ( I Think )

Well if it is non-linear that would lead me to suspect a hardware problem.

Those steps/mm numbers are correct so it must be something else.

You have the stepper currents set to 800. The would be appropriate if the steppers were spec'd at a max of 1000. Which doesn't seem likely.

Try upping the current to a max of 80% of the stepper rating. Maybe the steppers are just missing a micro-step here and there.

And the max speed setting of 180,000 seems rather high - that works out to 3000 mm/sec

Oh yes, one other thing - always put the M92 command before the M350 command and be sure the M92 command aris correct for X16 micro-stepping.

If you do that you can then change the settings in the M350 and the firmware will do the appropriate calculations for adjusting the steps/mm.

THANX everybody its all good now ❤
