Before You Start

Plan your installation before drilling holes

Read through all the installation pages first. The location of the controller box affects pneumatic line routing, wire lengths, and audio cable runs. Think about maintenance access — you'll need to reach the SD card slot and occasionally connect a USB cable.

Orientation Matters

The controller box contains an IMU that measures pitch and roll. You can mount the box in various orientations, but you must configure the orientation in software to match your physical mounting. See First-Time Setup for orientation configuration.

When done with installation, proceed to First-Time Setup to configure the system.
