Recently, we have one of the our matrice 600 arm broken. Because the motor itself is good, we think we only need to buy a new arm and save the overall cost (as in 1.png).

We find in order to properly install the arm, we need a calibrator (2.png) in order to align the arm to the motor with right angle. However, it is not clear how to use the calibrator. We cannot find any source to teach us online.

We also found the original arm is connected to the motor with two screws with round head and no slot. How can we safely remove them?

Any comment is appreciated.
