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.

Parameter Comparison

When using the ALPS pressure module, it is recommended to pair it with the wiper function to ensure nozzle cleanliness, thereby enhancing leveling accuracy and stability.

Secure Module Installation: Ensure the module is firmly installed to avoid poor contact caused by printing vibrations.
Proper Cable Connection: Carefully check the wiring to ensure it is correct, preventing module failure due to wiring errors.
Perform Leveling Test: Before first use, execute multiple leveling tests to verify whether the module's sensitivity and accuracy meet requirements.
Must Connect to Mainboard: Connecting only the TYPE-C cable and the pressure module will not allow it to work (including debugging). The module must be connected to the mainboard or tool board and activated in the console/software to function properly.

Prerequisite: The status light indication is only valid after the module is correctly wired and enabled in the console.
Power-On Status: The green and red frame status light stays on, indicating normal module operation.
Trigger Status: The red frame status light flashes, indicating that the module is in a triggered state.

If the status light does not illuminate, check whether the power wiring is correct.
If the status light continues to flash, the module may be detecting an abnormal signal. Check if the probe is stuck by debris or damaged.
