LX2: Z-Axis Not Moving or Moving Irregularly

If the Z-axis on your LX2 does not move or moves irregularly during operation, you may be unable to complete your project. If you are experiencing this issue, this article may help you troubleshoot it.

Possible Cause 1: Disconnected or Damaged Z-Axis Motor Cable

• Turn off the LX2.
• Check the connection cable between the Z-axis motor and the control board for any signs of a loose connection or damage.
• If the connection is loose, reconnect the cable. Restart the computer to check whether the issue has been resolved.

Refer to the Z-axis disassembly video below:

Possible Cause 2: Physical Damage to the Cable or Connector

• Turn off the LX2.
• Check the Z-axis motor cable for breaks or other damage. If it is damaged, replace the Z-axis motor cable.
• Check the pins inside the connectors on both the mainboard and the motor for bending or damage. If any pins are bent or damaged, replace the mainboard or the motor.

Possible Cause 3: Damaged Z-Axis Limit Switch

• Check the Z-axis limit switch for physical damage. To verify that it is functioning properly, manually trigger the limit switch and observe whether the Z-axis motor stops immediately.

Note: Before disassembly, we recommend manually moving the Z-axis to the upper-middle area first. Then perform the trigger test to prevent the moving assembly from colliding with the machine.

If the machine still does not operate properly or any cables are visibly damaged, contact LaserPecker Technical Support for further assistance. Please provide a detailed description of the issue and the troubleshooting steps you have already tried.
