SlicerIGT pivot calibration

Hello
I’m trying to use the pivot and the spin caliberation in the igt model, at first it worked fine but now it stopped working, do you have any idea what am I doing wrong?
I’m working with a needle model and a NDI aurora tracker via plus

Without more details, we can only guess.

My guess would be that the needle is already calibrated.

If you think that the problem is something else then please describe what you did, what you expected to happen, and what happened instead. Provide a screenshot of the transform tree (Data module, Transform hierarchy tab), a screenshot of the Pivot calibration module, and your Plus device set configuration file.

I managed to figure out what the problem was… thank you very much for your answer

Can you tell the forum readers please so everyone can learn from it?
