There is specific info on how to check backlash in Members Doc's. What you values you measure is what should be used in the Backlash settings under config.

Make sure your steps per unit are correct. They should be set based on the longest move an axis can move. That will minimise the error. Now check your steps per unit for
a shorter movement.....are they still the same? I don't know how your axis are driven and believe your problem is mechanical.

hi RICH yes shorter movemnt is corectly but.. i never try a longest move. yaa.. also i dont know why my step per unit like that 22.727373.. evertime is same.. and my Velocity is 15.000 acc. 200 is it have a balance or not... but i also use it 1 driver 2 step motor... dont know its avaible or not but.. driver is good one's yaa for 21NM use it before..
