Hello SkyFire,
Thank you for your answer. yes, I did it also in a similar way. The problem was that the Home Point (start point) had been taught based on Frame zero and the endpoint had another frame. so I set my Frames before doing the offset in order to have the right shifting and it worked. In Order to avoid repetition, I did it as a function and I called this function each time I need in my program.
Best regards
Ciao...
