What You See

When the issue happens, you'll see a pop-up error message that says the z-axis homing failed.

Why It Happens

The possible causes include:

• The z-axis photoelectronic sensor is stained.
• The z-axis interface board cable pins are stained or short-circuited.
• The laser module's flat cables are disconnected or damaged.

How to Fix It

#1 Clean the Z-Axis Sensor

1. Disconnect the power. Flip the M1 over. Get a cotton swab or a small brush to clean the sensor.

For details, please see the video below:

2. Make sure there is no foreign object stuck in the sensor.Hold the laser generator with your hand and push it upward to ensure the teeth on the laser module are in contact with the gears of the stepper motor.

3. Start the M1. If the cleaning worked, the laser generator will automatically rise. Be careful not to let your fingers get caught. If it doesn't work, try to clean it for a few more times. If the issue persists, move on to the next step.

#2 Clean the Z-Axis Adaptor Board's Cable Pins

1. Check if the metal pins in the socket and cable of the interface board are stained or cross-shorted.

2. Use a dry brush to gently clean the metal pins and sockets, then reinstall.

#3 Reconnect or Replace the Laser Module's Flat Cables

1. Check if the flat cables (see the picture below) are loose or damaged.

For details, please see the video below:

2. If the flat cables are loose, reinstall them. If the flat cables are damaged, provide pictures of the damage and contact the xTool support team for assistance.
