hi Sir ,
trying to descripe my question in different way. I've successfully syncronized robot with linear rail(7th axis) and positioner(8th axis) , how do I add one more positioner(9th axis) to be syncronized with 8th axis?

电的夫妇。我试着to bring 9th axis directly under 8th axis in tree structure, but seem not work in that way

May I have your advise?

You can synchronize a robot arm with up to 2 additional mechanisms. Each of these mechanisms can have a combined number of 6 axes (12 in total).

Can you share your RoboDK project? We may be able to help you better.
