Extensions TETRIX Getting Started Guide Servo Horn Adjustment Note: Whenever a servo motor is used to attach an extension, care must be taken to properly adjust the servo motor position so that the desired range of motion is achieved. The best way to adjust the servo position is to unscrew the servo horn and use it, and the extension that has been built onto it, like a wrench. Step 1 Starting Point: Attach the servo horn to adjust the servo position. Step 2 Rotate: Rotate the servo so that it has been positioned at the end of its range of motion. Step 3 Final Positioning: Reattach the servo horn with the extension piece in the appropriate position for that servo location. 229
