Why Does My LONGER RAY5 10W Show a Limit-Switch Alarm?
Exact model: LONGER RAY5 10W
Safety: Disconnect power before opening the controller or laser head. Use wavelength-appropriate laser eye protection for testing.
A.
Start with the accessible checks
What this suggests: A RAY5 10W limit alarm can be an actual endstop hit, obstructed carriage, damaged limit harness or an incorrect homing configuration.
What to do
- Power down, clear the gantry path and inspect both axes for loose cables or debris.
- Check the physical endstop actuator and connection against the correct RAY5 10W wiring layout.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- With the laser disabled, use supported controller status to verify the switch reports only when actuated.
- Fix a bent switch mount, crushed wire or loose connector; do not paste unverified GRBL settings or permanently bypass travel limits.
Confirm the repair
The head homes once and retracts normally without limit alarm and without moving into the frame.
