How to Fix It

#1 Clean the X-axis sensor

1. Disconnect all cables and flip M1 upside-down.
2. Clean the sensor with a cotton swab or a small brush, as a dirty sensor can cause malfunction.
3. Make sure there is no foreign object stuck in the sensor.

For more details on how to clean the sensor, please refer to the video below:

#2 Correct the X-axis sensor probes

1. Move the laser module to the far-left position.
2. Remove the laser module protective cover and check if the sensor's probe can pass through half of the X-axis position limit piece. 
3. If not, gently adjust the sensor probe to the left to make sure that it can pass through.
4. If this is not the case, proceed to the next step.

#3 Correct the X-axis position limit piece

1. Move the M1 laser module to the far-left position.
2. Check if the position limit piece can be inserted smoothly into the square hole of the laser module (see the picture below) and into the left side of the X-axis photoelectronic sensor probe.
3. If not, this indicates a deformation of the position limit piece. Please straighten the position limit piece.
4. If this is not the case, move to the next step.

#5 Replace the laser module fixing piece

1. Check if the laser module is wobbly. 
2. If so, this suggests a malfunctioning laser module fixing piece. Please contact xTool Customer Service for a replacement.
