Background Information
The Bambu Lab A1 mini is a compact desktop 3D printer designed as a user-friendly, feature‑rich gateway to 3D printing. With a build volume of 180 × 180 × 180 mm and a steel and extruded aluminum chassis, it combines Dual-Core Cortex M4 motion control with full-metal linear rails for high-speed precision—ability to reach 500 mm/s and 10,000 mm/s² acceleration.
It supports the AMS lite multi‑filament system for easy color prints, and extensive automation features including auto bed-leveling, Z-offset calibration, resonance tuning, filament loading/unloading, belt tension monitoring, and even pressure‑based flow calibration per print.
