The tension of belts will be the same as they are connected through X carriage, but if one belt is longer than other you will get a skewed structure.Quote

I even check the tension of the belt using the precise weight and pressing it to a specific point. It's pretty the same.
This gap between perimeters clearly shows that X is not perpendicular to Y as your diagonal length 1 is longer than 2.Quote

As you see, there is a gap in the wall in 45degree and the wall on second 45 degree axis is too tight.

You may see the effect of belts tension if you move Y to max or to 0 and apply extra tension by hand to one of the belts - your Y carriages will move along Y in opposite directions.

I was referring to the symmetric systemQuote

If motor B was moved up and segments A and J were longer, it would not affect operation of the mechanism. As long as segments A-H are parallel to the guide rails, and the belts have tension set to keep the X axis square with the Y axis, the mechanism will work fine.
...
Equal belt length is completely unnecessary.
