Let us start with this one first. It is the model and an IK-XML-file.
Because I expect that it will not work again, I tell you what I have done: I have clicked Attachments below, have added a zipped file of 19kb. It appeared in the attachment list. Now I click the submit button.

At the Moment I am sticking with a strange behaviour of the model when running the inverse Dynamics sequence. In the kinematics Animation all segments stay together as expected. In the ID there is a big displacement between Segment 5 and 6.
I was able to replicate this behavior. I think it has to do with naming all your new coordinates the same thing ('_zTranslation', 5 times). I gave each independent coordinate its own name ('joint5_zTranslation') and unlocked all the coordinates during ID — which solved the problem. I have attached the updated model.

Thank you James,

nice Christmas gift. It works fine now. First there was still a shift in the jointsbut when I reduced the translation ranges it run perfectly.
