CRITICAL: like every Bambu, requires use_relative_e_distances (M83) and EMPTY start/end gcode - Kiln's bambu_3mf module injects BambuStudio's proprietary init/end sequence; without it G1 E moves are silently ignored. NOT YET hardware-proven on the A2L (mirrors the A1 profile, same kinematic class); the A2L may need its own BambuStudio machine init sequence once that profile ships - verify before relying on it.",
