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.
Dimensions
Compact design with extra heat dissipation capabilities.
- Dimensions: 64 x 58 x 16.5mm
- Weight: 87g
Control software
SCE2-MOTION can be controlled by any G-code sender like Candle, Universal-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.

Firmware
Firmware is open-source GRBL based running on STM32 microcontroller.
Schematics
SCE2-M module
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.

Power supply
Controller can drive up to 1.2A per channel, thus max power demand when all 4 motors are driven at 100% power will not exceed 5A @ 9V DC.
