# SCE2-MOTION # Overview **SCE2-MOTION** is a compact controller designed for robotic photography, controls [motor actuators](https://wiki.kurokesu.com/shelves/motion-actuators), and triggers DSLR camera. It is based on 4 channel stepper motor controller [SCE2-M](https://wiki.kurokesu.com/books/sce2) module. The controller is running open-source [GRBL firmware](https://github.com/Kurokesu/SCE2-GRBL) capable of advanced scripting and complex movements.

Most of these software packages lack the g-code generator part. So highly specialized open-source programs had to be created from scratch. #### RSB1 360 product photography - Source code on [GitHub](https://github.com/Kurokesu/RSB1_360_product_photography) - Windows releases also on [GitHub](https://github.com/Kurokesu/RSB1_360_product_photography/releases) - [More details](https://wiki.kurokesu.com/books/motion-control-software) about motion control software Code is written with Python it can be run on any modern operating system, even Raspberry Pi# Default GRBL settings Each actuator combination needs individual settings to be fine tuned.

Controller is shipped with connected optocoupers (safe to connect to expensive DSLR camera). But for ease of customization control signals can be wired directly. See not populated resistors.
