I put the TRY_PD back to the end table and aligned it. Now it seems to be working well.
The PD Kiwamu removed from the Y table was TRY, which we still need.
My bad if he took that. By mistake I told him that was the one I installed on the table for the length measurement and we didn't need it anymore.
I'm going to ask Kiwamu if he can kindly put it back.
I am going to put the PD back to the Y end table in this afternoon.
