The tool can be aligned to the rotational axis of the universal module by adjusting the set screws on the lower part of the tool body. This allows the microscope to be used for accurate registration tasks (in addition to simple measurement and inspection tasks, for which alignment isn't necessary).
TODO: write detailed instructions.
## TODO
## Future tasks
1. Make a startup service that starts the webcam server. Need to issue the shutdown command via the webpage to avoid potential corruption of SD card.
2. Would be great to adjust field of view without disassembling the scope. Maybe as simple as an access hole for adjusting knob.
