Description
The “Servo” object is used to interface with servos used with the builder base. You can do this by passing the servo object a number through the “Degrees” ports. The other two ports, “0 Offsets” and “180 Offsets” are reserved for modifying the Servo’s range of motion.

2 | 0 Offsets | Number | Offset setting for the 0 degree position. Since every servo is slightly different in its control, this setting allows you to level the servo at the exact 0 positionThe 0 Offsets is used to calibrate the position of a servo on the 0 degrees end of the position range. |
3 | 180 Offsets | Number | Offset setting for the 180 degree position. Since every servo is slightly different in its control, this setting allows you to level the servo at the exact 180 position. |

The 180 Offsets is used to calibrate the position of a servo on the 180 degrees end of the position range. |
Offset Adjustment
The 0 and 180 offsets are used to calibrate the position of your servo arm for a given degree. You can feed both of the offsets ports offsets ranging from [-30, 30].
To properly execute the initial calibration of your servo, you should send your servo to the 90 degree position and then attach the servo arm at a 90 degree angle to the servo body. Next, send your servo to the 0 degree position and then to the 180 degree position. If your servo moves -90 degrees to the 0 position and +90 degrees to the 180 position then your servo does not need any calibration. However, if your servo does not move all the way to the 0 position and is shy by a few degrees, you can input a positive number into the “0 offsets” port to extend its range of motion. Or if the converse is true, and the arm extends past what should be the 0 position, you can limit its range with a negative number in the 0 offsets port.
The same is true with the 180 offsets port. If the servo moves to a position less than 180 degrees, you can extend its range with a positive number, and if it moves more than the 180 degrees you can limit its range by feeding the port a negative number.
To properly do the initial adjustment for the servo, the arm should be attached to a 90 degree position when the servo degrees are at 90 as well. Then, when we go to for example 0 and the servo does not do total negative 90 degree movement, we can adjust wi with the 0 offset port. Here we can enter an number between 0 -30 and 30. If the server moves not far enough, we can extend its range with a positive number and in case it overshoots, we can hold it back with a negative number. The same is valid for the 180 degree position, just that we use the 180 offset port here.
