Introduction
* The ALPS pressure module is a pressure sensing solution designed based on the ADS131M02, specifically developed for automatic Z-axis homing and mesh bed leveling in 3D printers. By utilizing high-sensitivity pressure detection and real-time signal processing, the module can accurately sense the contact status between the print head and the bed, achieving millimeter-level leveling precision, eliminating errors from traditional mechanical limit calibration, and significantly improving first-layer printing success rates.

FAQ
Please note: Sending SETPIN PIN=probe_ready VALUE=0 will, regardless of the situation, not cause the light on the sensor end to turn on. If the light is on or flashing, it indicates an issue with the wiring or configuration of the EN pin.
