3D Touch Auto Bed Leveling Sensor is a high-precision automatic bed leveling sensor designed to improve first-layer adhesion and printing accuracy. It uses Hall-effect sensing technology with a retractable probe to measure multiple points across the print bed and automatically compensates for surface irregularities. Compatible with most open-source 3D printers and BLTouch-supported firmware, it provides reliable, repeatable, and accurate bed leveling for consistent print quality.
