Level the slider first, then support it at both ends on two light stands or a tripod and the included feet. Move the carriage at an even speed, start and stop gently, and use a light camera and lens: the less weight on the carriage, the smoother the move.
Portable motion control
At 80 cm, the ER1 fits in a backpack and still gives meaningful moves. The app runs manual, video and time-lapse modes, and the silent stepper motor keeps noise down for interviews.
Box contents
The bullets say no charger is included, while the product table lists a four-channel charger and a 100 W fast charger. Check the box on arrival.
