Optimal settings in HC

Dear College!
I need some help to find the optimal limitation numbers in the movement of my rig with wd20to avoid crash and nirvana at the night. I attached a picture for realize the rig.
Could you send me correct limit numbers to excape from the mount crash during the movement… Yes I know that I need a pier extension … This is on progress …
