Braccio tinkerkit robot - initial / safety position wrong

Hi, I tried to run testbraaccio90 scetch but the Braccio just collapsed on the table before it make the move to the direct position (still about 5 dec wrongly). If I set initial settings by hand it finally reach the safety position after Braccio collapsed to the table:

Braccio.ServoMovement(20, 90, 45, 180, 180, 90, 10);

What could be wrong?
