PhotoRobot Laser Centering & Alignment Guide

‍

This user support manual provides technical instructions on how to align and center PhotoRobot built-in cross laser systems. Follow these steps to find the midpoint of any round PhotoRobot plate using two lasers. Instructions include how to physically move the lasers to the center of the table, initial laser settings, and how to fine-tune laser positioning. Additionally, at the end of the manual, there are instructions for aligning and centering the special laser system of the C1300 turntable (previously distributed under the name Case 1300). 

Important: Always first refer to PhotoRobot Safety Information & Instructions in addition to the manual provided specifically with your device before any self-installation or service.

Note: Refer to PhotoRobot First Use & Basic Testing for detailed information on network configuration, and network requirements.

‍

1. Physically Move Lasers to Center of Table

1.1. Before getting started, establish a connection between the PhotoRobot and the local network. Next, power on the Control Unit (6th Generation), and a laser-box.

Note: To align and center the laser system for the C1300 turntable, also refer to the special instructions in section 4 of this user manual. 

1.2. After connecting PhotoRobot to the network and powering on the Control Unit and laser-box, measure the distance between both sides of the table where the laser is mounted. Then, turn or move the laser by hand to the center, and fasten the laser into position.

2. Estimate Rough Settings

2.1. When the laser is fastened into position, place a sticker onto the turntable plate at the approximate midpoint of the glass. The lasers will become more visible on the sticker, helping to better estimate the central point of the plate. 

2.2. Adjust both lasers by hand to align on the sticker which estimates the approximate midpoint.

‍

3. Fine-Tune Laser Alignment

3.1. Trace a small cross on the sticker copying the red cross of lasers.

‍

‍

3.2. Next, start the Locator application on your mobile phone, find the Control Unit assigned to the robot, and access the service GUI. Note: For detailed instructions on networking, refer to the document PhotoRobot Detailed Networking Prerequisites (page 31, Appendix 1). Then, find the Control Unit assigned to the robot, and access its GUI.

‍

‍

3.3. In the Service GUI, use the turn controls to rotate the glass 90 degrees, and trace the position of the cross lasers onto the sticker again. Repeat this step twice: rotating the glass 90 degrees, tracing the laser cross, rotating 90 degrees, and tracing the laser cross a final time. 

‍

‍

3.4. After tracing the four crosses on the sticker, connect each opposite cross by straight lines. The resulting cross in between the individual crosses will represent the actual midpoint of the glass plate. 

‍

‍

3.5. Finally, adjust both lasers to the identified midpoint. The laser system will now be centered and aligned to the absolute center of the plate’s rotation.

4. C1300 Specialty Lasers Alignment & Centering

4.1. When aligning and centering the lasers on the C1300 robot, note the specialty laser system. The C1300 laser system has several differences in comparison to other PhotoRobots. Although the physical principles are the same, the construction of the C1300 laser system features an installation of four lasers.

‍

‍

4.2. In this system, Laser 4 is an integral part of the C1300 robot skeleton. Laser 4 is a cross laser, and it shines through the white background from the bottom side. To adjust the laser position, find the four silver screws to uncover the central square part housing the laser.

‍

‍

4.3. After uncovering the central square part housing Laser 4, use the two screws holding the plastic laser housing to adjust its position manually.

‍Note: Laser 1, Laser 2, and Laser 3 all have the same construction as Laser 4. They are also all line lasers:

‍

‍

4.4. Finally, when aligning and centering the lasers, ensure there is a 90-degree angle between the laser line from the top laser and the glass plate.
