#### 3D models

<p class="callout info">3D models can be downloaded from [GitHub](https://github.com/Kurokesu/3d_models)</p># Control software

SCF4-SDK comes with open-sourced command line and GUI sample programs for rapid controller evaluation. A simple control software example is provided for testing and demonstration. Software is given "as is" to help with getting started and testing.

**More details and control explanation in [SCF4 documentation](https://wiki.kurokesu.com/books/scf4/page/demonstration-software).** Source code is maintained on [GitHub](https://github.com/Kurokesu/SCF4-SDK)

Where:

1. Com port is open and controller initialized
2. IR filter switched on and off several times
3. IR light switched off and on two times
4. Regular motor operation. Homing and toggle between few presets

### C1 PRO camera
