SCE2-MOTION

Fully integrated 4 axis motion controller for automated photography

Overview

SCE2-MOTION is a compact controller designed for robotic photography, controls motor actuators, and triggers DSLR camera. It is based on 4 channel stepper motor controller SCE2-M module. The controller is running open-source GRBL firmware capable of advanced scripting and complex movements.

Control software

SCE2-MOTION can be controlled by any G-code sender like CandleUniversal-G-Code-Sender, and many more. Most of these software packages lack the g-code generator part. So highly specialized open-source programs had to be created from scratch.

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. Below settings are for:

DSLR control headers

SCE2-MOTION has 4 outputs available. 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.
