3. Next, install the pivot stand onto the Romi expansion platform using two 8 mm M3 screws and M3 nuts. The nuts should be seated into the cut-outs in the base of the stand.

5. While the servo is easily accessible, now is a good time to install the short linkage on the lift servo horn. Start by aligning the linkage and inserting a 6 mm nylon spacer through the hole on both parts. Then, insert a 3/8″ #2-56 screw with a washer through the spacer and secure it with a #2 nut on the other side. All of the joints on the arm will use this same method (with appropriately sized screws and nylon spacers).

6. Use one of the servo mounting brackets to secure the lift servo to the right side of the Romi expansion platform using two 8 mm M3 screws and M3 nuts. The nuts should seat into the cutouts on the underside of the Romi expansion platform.

7. Prepare the tilt servo by using your servo controller to command it to move to its starting position (1200 µs pulse duration), then install the tilt servo horn with the included mounting screw, making sure it is aligned as shown.

8. Use the other servo mounting bracket to secure the tilt servo to the left side of the Romi expansion platform, again using two 8 mm M3 screws and M3 nuts.

9. Use a 20 mm nylon spacer, 1″ #2-56 screw, a washer, and a #2 nut to install the main arm to the pivot stand as shown.

10. Use a 20 mm nylon spacer, 1″ #2-56 screw, a washer, and a #2 nut to install the main arm to the pivot stand as shown.

11. The next step is to install the two triangular pivot transfer linkages, one on either side of the main arm, making sure the direction indicator arrows are facing forward. Use a 20 mm nylon spacer, 1″ #2-56 screw, a washer, and a #2 nut to secure the 3 components together using the bottom-most hole in the triangular pivot transfer linkages.

12. Connect the rear tilt arm to the top of the triangular pivot transfer linkages (again using a 20 mm nylon spacer, 1″ #2-56 screw, a washer, and a #2 nut). Then, secure the other side of the rear tilt arm to the tilt servo horn using a 6 mm nylon spacer, 3/8″ #2-56 screw, washer, and #2 nut.

13. Using a 20 mm nylon spacer, 1″ #2-56 screw, a washer, and a #2 nut, connect the front tilt arm to the last available mounting holes on the triangular pivot transfer linkages, ensuring the direction indicator arrow on the underside of the front tilt arm is pointing forward.
