The Linear Module can only move in one direction.
- The end-stop switch is stuck.
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 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 or Z Linear Modules might be stuck. Since Y and Z axes each have two Linear Modules, you can test one of them at a time to find out which Linear Module is faulty.
3. Fix the end-stop switch on your TRIGGERED Linear Module.
3.1 Disassemble the cover (the one with no cable end) of the Linear Module. You will need the 2.5 & 2.0 hex screwdriver.
3.2 Find the end-stop switch. Check if it's stuck.
3.3 Tap the end-stop switch and re-assemble the Linear Module.
4. Check if the Linear Module works. If not, replacing the Linear Module might solve the problem.
