BD Sensor VB — Eddy Bed Distance Sensor

Description

BD Sensor VB — Eddy Bed Distance Sensor

The BD Sensor VB is a compact, high-precision eddy-current sensor that measures the distance between the nozzle and the print bed in real time. Designed as a drop-in upgrade for most 3D printers, it enables automatic bed levelling, live Z-offset adjustment, and real-time distance display on your printer’s screen.

Key Features

• Fast bed scanning — quick mesh levelling across the entire build surface
• Contact probe accuracy — ±0.005 mm repeatability
• Real-time levelling — continuous Z compensation during printing
• Distance display — live nozzle-to-bed distance on your screen
