BEACON EDDY CURRENT SURFACE SCANNER The world’s first 3D printer surface scanner for a sub-micron bed mesh in seconds. Beacon RevD Modular First Generation ORDER NOW Beacon RevH Accelerated Second Generation PRE-ORDER NOW Nervous about your first layer? Beacon is so fast, it scans right before the first layer, measuring exactly what you’re printing on. 1 ATTACH Attach the 3.5g Beacon to your printer toolhead. 2 SCAN Scan your bed in 20 seconds or less with 0.5µm (0.0005mm) resolution. 3 PRINT Print with the confidence of a precise last second scan. Fast Surface Mesh Beacon directly measures distance for rapid mesh construction at up to 500mm/s, without ever moving the z axis. LEARN MORE Uncompromising Precision Meticulously optimized to achieve 0.5um resolution at 1k samples per second with <350nm typical standard deviation. LEARN MORE High Temperature Rated up to 115°C ambient and designed for minimal thermal drift and equipped with active temperature compensation. LEARN MORE On-Board Accelerometer Klipper’s first high temperature rated accelerometer for simplifying resonance measurement and compensation.
