trying to draw a circle but it is not working

[jetixmen]

Hello i have watched a video of Pranav Bhounsule (it is same version of CoppeliaSim) and i copied it. Everything are some but somehow it works different. İ digged it some and i think i found the point that difference occur, locations of the center of the sphere that we choose for our trajectory (i am not sure the main problem is this or not). Center's x coordinates are same and true but Y coordinates are different, i can't understand why. Z coordinates are different too but it is normal.
All in all thats all i can say, i can use the Pranav Code directly but i want to learn why my code is not working.
it is Pranav's scene: https://drive.google.com/file/d/1PZBEFe ... drive_link
it is my scene: https://drive.google.com/file/d/1oFhJEz ... drive_link
Very very thanks in advance.

There are several things that are not the same. But the most important is that in the initial configuration, the first joint is at 120 degrees in the first scene, but at 30 degrees in the second scene.
