Laser Module Hits Edge on Return to Home — Ray5 MiniS

When the laser module hits the edge during the Return to Home process, it usually indicates a limit switch or homing issue. This can affect positioning accuracy and may cause repeated mechanical stress on the machine if not resolved.

This guide helps you identify and fix the most common causes of this issue on the Ray5 MiniS.

1. Check the Limit Cable Connection

• Inspect the limit switch cable connection
• If the cable is loose or partially disconnected:
  • Secure and tighten the connection
• Ensure all connectors are firmly plugged into the mainboard

2. Check the Limit Switch Position

• Verify whether the limit switch position is too far back
• If the switch is not triggered at the correct time during homing:
  • The laser may continue moving and hit the edge

How to Fix:

• Adjust the limit switch position so it is triggered just as the machine reaches Home
• Ensure proper alignment between the switch and the trigger point

Conclusion

Laser module edge collisions during homing are typically caused by loose limit switch connections or improper switch positioning. By ensuring secure cable connections and correctly positioning the limit switches, you can restore safe and accurate homing behavior.

Proper calibration of the homing system helps prevent mechanical damage and ensures precise positioning for all engraving tasks.
