USO datapacket, Servmotor from 90° to 180°

[lomantmic]

Hi, I just registered in this forum.
I have a problem I have to solve:

I built a 6DOF with serve motor (PWM) and use the Pololu Maestro card to move the motors. I was able to move the motors but currently moving only 90 degrees. How can I convert the movement of the motors serves 180 degrees?

Thanks
Antonio
