What should I do if the Linear Module can only move in one direction? – Snapmaker

The Linear Module can only move in one direction.

Possible Cause

The end-stop switch is stuck or broken.

Actions

1. Connect the machine to your computer with a USB cable.

2. Launch the Snapmaker Luban. Go to Workspace, input M119 in the Console panel, and then check the status of the end-stop switch.

If X_min or X_max is displayed as “TRIGGERED” (as opposed to “open”), then the end-stop switch of the X-axis Linear Module might be stuck.
Similarly, if Y_min, Y_max, Z_min, or Z_max is displayed as “TRIGGERED” (as opposed to “open”), then the end-stop switch of the Y-axis or Z-axis Linear Modules might be stuck. Since both Y and Z Axes have two Linear Modules, you can test one of them at a time to find out which Linear Module is malfunctioning.

3. Fix the end-stop switch of your TRIGGERED Linear Module.
