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 remember: Sending SETPIN PIN=probe_ready VALUE=0, under no circumstances should the light on the sensor end illuminate. If the light is on/blinking, it indicates a wiring/configuration issue with the EN pin.
