Introduction

The ALPS Pressure Module is a pressure sensing solution based on the ADS131M02, specifically developed for 3D printer automatic Z-axis homing and mesh bed leveling. Through high-sensitivity pressure detection and real-time signal processing, the module can accurately sense the contact state between the print head and the bed, achieving millimeter-level leveling accuracy. It eliminates errors from traditional mechanical limit calibration and significantly improves the success rate of the first layer print.

Parameter Comparison

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

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

Prerequisite: The status LED indication is only valid when the module is correctly wired and turned on in the console.
Power-On State: The green and red frame status LEDs are steadily lit, indicating the module is operating normally.
Triggered State: The red frame status LED blinks, indicating the module is in a triggered state.

If the status LED does not light up, check if the power wiring is correct.
If the status LED blinks continuously, the module may be detecting an abnormal signal. Check if the probe is stuck by debris or damaged.
