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.
