Hello
I have been trying to figure out how to reset a servo's default 90, my robot head turns almost 180 degrees to the right and 5 degrees to the left.
I tried the screw, and re aligning but its clear the motor thinks its at 90 when its closer to 180. how do you reconfigure a servo's set 90 position?
The servos position is taken from the servo, if it thinks it's at 180 it is at 180. The only way this would not be the case is if the servo itself is damaged and the internal pot is no longer being moved by the servo. Replace the servo.
If you do not want to replace the servo for whatever reason repair of the servo may be possible however I would still recommend replacing the servo as, by asking the question it is clear you are not knowledgeable enough to repair the servo - it's not an easy task.

For example, you set the servo to 90. That moves the servo to what it knows as 90. If the bracket does not match up to 90, then you have to calibrate the bracket.
Maybe the lessons should be called calibrating brackets
is it possible that a servo doesn callibrate good?
and how can you see that.
Out of curiosity i figured offset the calibration to see where the real problem is so i hooked up his head to be positioned off the the right so that hopefully it would allow me to let the head turn further to the left by using the calibration tool in windows to say -22 so his head was straight but instead when it got to the point it would normally stop at it started jamming saying it was past its max and i stooped it.
is the head meant to turn further in one direction then the other?
You are in Calgary, are you not? Maybe drop by the office and we can help you. I'll be around tomorrow day. Or I can meet you tonight after my plane lands from Seattle after 7 pm
So it's just this one? That seems to change its 90 degree position?
The little potentiometer inside reports the position. There is usually a screw holding it in place.
