Servo not going 180 degrees

Evening all,

I have a set of TowerPro mg995 and they work fine in the sense they move but they dont go the full 180 degrees.

I think its a case of adjusting the myservo.attach call to include the correct microseconds settings for the servos but googling it hasnt brought any sucsess.

Has anyone else had this issue and resolved it?

Thanks

Dean

Some do 180 degrees, some don't.
Usually in R/C models, driving a crank through 180 degrees is not such a great idea, so the servos simply don't allow it.
By all means, try adjusting the timing.

Yes, 120 degrees might be a more common maximum travel. The 'official' servo travel is that which happens between 1 msec and 2 msec pulses, but most servos allow a some amount of over travel below 1 msec and above 2 msec.

So all you can do is experiment a little to categorize your specific servo.
