It may be worth checking the motor coupling. You should be able to remove the four cap head screws & pull the motor out. Depending on the age it will either have a Oldham Coupling or a split pin.

i checked the motor coupling , it is no problem
i checked the 2 limit switches on the other side from the turret
i seems the problem is the round cam activating the limit switches
the cam is contentiously pressing on the zero point limit switch , i will reduce the diameter of the cam and check again the result

The 2 microswitches are mounted on a plate that is movable. It`s fastened on with 3 cap head screws.
