Introduction
- The ALPS pressure module is a pressure sensing solution based on the ADS131M02 design, specifically developed for automatic Z-axis homing and mesh bed leveling in 3D printers. With high-sensitivity pressure detection and real-time signal processing, the module can accurately sense the contact status between the print head and the build plate, achieving millimeter-level leveling accuracy. This eliminates the errors associated with traditional mechanical limit switch calibration and significantly improves the success rate of the first layer printing.

ALPS Pressure Module Notes
Recommended Use with Nozzle Wiping Function
- When using the ALPS pressure module, it is recommended to use it in conjunction with the nozzle wiping function to ensure nozzle cleanliness, thereby improving leveling accuracy and stability.
Installation Notes
- Secure installation: Ensure the module is securely mounted to avoid poor contact due to printing vibrations.
- Correct cable connections: Carefully check all wiring to ensure there are no errors, preventing the module from malfunctioning 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 be connected to mainboard: The module will not function (including debugging) if only the TYPE-C cable and pressure module are connected. The module must be connected to the mainboard or an adapter board, and must be enabled via the console/software to function properly.
Status Indicator Lights
- Prerequisites: The wiring must be correct and the module must be enabled in the console for the status lights to work properly.
- Power On Status: A solid green and red indicator light means the module is functioning normally.
- Trigger Status: A flashing red indicator light means the module is in a triggered state.

Troubleshooting Indicator Lights
- If the indicator light is off, check whether the power wiring is correct.
- If the indicator light is continuously flashing, the module may have detected an abnormal signal. Please check whether the probe is jammed or damaged.
