About this model

A compact, cost-effective 3DOF motion simulator actuator setup inspired by the SFX-100 and SRT80 projects, redesigned specifically for apartment and residential use. Instead of bulky, loud industrial AC servo drivers and high-voltage wiring, this build utilizes NEMA 23 closed-loop stepper motors (3Nm / 180W) running at 48V DC. The system delivers up to 130 mm/s of dynamic speed with a safe, optimized 50 mm stroke—delivering responsive pitch, roll, heave, and haptic feedback without requiring dedicated electrical modifications. Key Features - Residential-Friendly: Compact footprint based on 80x80 heavy aluminum profiles, quiet operation, and standard residential power consumption. - Control System: Powered by an ESP32 microcontroller running custom firmware with multi-core serial communicat…
