After connecting to XCS, if a pop-up error message displays "Y-axis homing failure (error code Qx14 2)" while the button indicator light turns red with a loud sound as the laser module bumps into the front cover, this indicates a Y-axis reset failure. Please consult this guide for troubleshooting advice.

Possible causes include:

1. Disconnect M1's power cable and flip it upside down.
2. Check for any dirt on the Y-axis sensor (see the picture below).
   • If any, brush-clean the sensor with a cotton swab or a small brush.
   • Ensure no foreign object is stuck in the sensor.
3. If this does not resolve the issue, proceed to the next step.

1. Check if the X-axis gantry (see the picture below) is parallel to the machine body.
2. If not, correct it according to the following instructions:
   • Hold the right end of the X-axis gantry and push it slightly hard against the rear cover, as indicated in the picture below.
3. If this is not the case, proceed to the next step.

1. Power off M1.
2. Slide the X-axis gantry back and forth along the Y-axis back and forth multiple times to check for any obstructions in the Y-axis movement.
3. When M1 is connected with an Air Assist Set, ensure that the X-axis gantry is not caught by the air tube. Otherwise, adjust the tube accordingly.
   
4. If no Air Assist Set is installed and the Y-axis movement is obstructed, this may indicate the presence of foreign objects on the Y-axis guide rails. In such cases, attempt to invert the M1 to remove any foreign objects.
