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

Beacon RevH

Accelerated Second Generation

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.

RevD-her

Uncompromising Precision

Meticulously optimized to achieve 0.5um resolution at 1k samples per second with <350nm typical standard deviation.

High Temperature

Rated up to 115°C ambient and designed for minimal thermal drift and equipped with active temperature compensation.

Mesh-her
Graph-her

On-Board Accelerometer

Klipper’s first high temperature rated accelerometer for simplifying resonance measurement and compensation.

2nd Generation Design​

Optimized materials and design achieve +15% sensitivity, -40% thermal drift, and improved durability against minor abrasions.
