What This Guide Covers
This tutorial explains how to troubleshoot common engraving errors and alarms on the LONGER Ray5 MiniS laser engraver.
You will learn how to:
Prevent limit trigger alarms
Understand normal alarm behavior after stopping engraving
Fix overscan-related soft limit errors
Adjust coordinate settings properly
Resolve homing and zeroing abnormalities
Improve engraving stability and workflow reliability
The procedures below follow the original operating sequence and troubleshooting methods provided for the Ray5 MiniS.
Quick Answer
If your Ray5 MiniS displays engraving alarms or motion control errors:
Do not manually move the laser during engraving
Alarm reporting after pressing Stop is normal
Change coordinates to absolute coordinates if overscan triggers soft limits
Reduce the pattern size and place it in the middle if needed
Turn off the overscan function when necessary
Confirm the XY axis does not continue pressing the limit switch after zeroing
Most Ray5 MiniS engraving errors are caused by software settings or operation behavior rather than defective hardware.
Why This Process Matters
Laser engravers rely on accurate positioning and coordinated movement to complete engraving tasks safely and precisely. When the Ray5 MiniS detects unexpected movement, excessive travel range, or abnormal limit switch signals, it may stop the engraving process and report an alarm.
Understanding these alarms is important because it helps:
Prevent interrupted engraving jobs
Protect the machine from positioning errors
Improve engraving consistency
Reduce material waste
Avoid repeated homing failures
Maintain accurate motion control
Many beginners assume that engraving alarms indicate hardware damage. In most cases, the issue is related to machine operation, coordinate setup, or overscan configuration.
Before You Start
Requirements
Before troubleshooting Ray5 MiniS engraving errors, prepare the following:
LONGER Ray5 MiniS laser engraver
Connected engraving software
Properly powered machine
Stable working surface
Correctly installed limit switches
Engraving design file for testing
Follow official machine specifications or instructions.
Precautions
Before performing troubleshooting procedures, keep these precautions in mind:
Do not manually force the laser module during engraving
Keep hands away from moving parts
Monitor the engraving process continuously
Verify coordinate settings before engraving
Ensure the machine frame moves smoothly
Avoid interrupting engraving unnecessarily
Incorrect movement or positioning may trigger unnecessary alarms and stop the engraving process.
Step-by-Step Tutorial
Step 1: Prevent Limit Triggering During Engraving
Original Step
Manually moving the laser position during engraving causes limit triggering.
Action
Do not manually move the laser position while engraving is active.
Expected Result
The engraving process should continue normally without triggering a limit alarm.
Important Notes
The Ray5 MiniS continuously tracks the laser head position during operation. If the laser module is manually pushed or repositioned while engraving, the controller may detect abnormal movement and trigger a limit alarm.
This issue commonly occurs when users attempt to adjust material positioning during engraving.
If the machine reports a limit error:
Stop the engraving process
Reposition the laser correctly
Restart the engraving job if necessary
Avoid touching the laser assembly during operation.
Step 2: Understand Stop Button Error Reporting
Original Step
When you click Stop during engraving, this error will be reported, which is normal.
Action
If you press the Stop button during engraving and an error appears, understand that this behavior is expected.
Expected Result
The engraving stops immediately and the system reports an alarm or error message.
Important Notes
This is normal machine behavior rather than a hardware malfunction.
When engraving is interrupted manually, the controller detects the interruption and reports the stop condition as an error or alarm.
After stopping:
Clear the alarm if required
Reset the engraving position if necessary
Restart the engraving task
If alarms continue after restarting, verify the coordinate settings and engraving area configuration.
Step 3: Fix Overscan and Soft Limit Errors
Original Step
When engraving an image or vector filling at the current position, if the overscan function is turned on, the soft limit may be triggered, and the engraving may not be possible. You need to change the coordinates to absolute coordinates. If you do not change the coordinate system, then reduce the pattern and put it in the middle, or turn off the overscan function.
Action
Adjust the coordinate system or overscan settings when soft limit alarms occur during image engraving or vector filling.
Expected Result
The engraving process should complete without triggering soft limit errors.
Important Notes
This is one of the most common Ray5 MiniS engraving problems in engraving software.
Overscan allows smoother acceleration and deceleration by extending movement slightly beyond the engraving boundary. However, when the design is placed too close to the machine edge, overscan movement may exceed the available work area and trigger a soft limit alarm.
Follow the original troubleshooting sequence exactly:
Change the coordinates to absolute coordinates
If the coordinate system is not changed, reduce the pattern
Put the pattern in the middle
Turn off the overscan function if necessary
Do not modify additional machine parameters unless instructed in official documentation.
Follow official machine specifications or instructions.
Step 4: Resolve Zeroing Abnormalities
Original Step
The machine continuously detects the signal of the limit switch, resulting in a zeroing abnormality. The solution is to confirm that the XY axis does not hit the limit switch after the XY axis completes zeroing.
Action
Check the XY axis position after zeroing completes.
Expected Result
The machine should complete homing normally without repeatedly triggering the limit switch.
Important Notes
This issue occurs when the controller continues receiving a limit switch signal after the homing process finishes.
Possible causes include:
The XY axis remaining pressed against the limit switch
Mechanical obstruction
Incorrect positioning after homing
Axis movement restriction
Carefully inspect the machine after zeroing completes.
Verify that:
The XY axis moves away from the limit switch normally
The carriage is not stuck
The machine frame moves freely
No obstruction blocks axis movement
If homing abnormalities continue:
Restart the machine
Recheck the limit switch area
Confirm smooth axis movement
Avoid manually forcing the carriage while the machine is powered on.

Frequently Asked Questions
Why does my Ray5 MiniS trigger a soft limit alarm?
Soft limit alarms usually occur when overscan movement exceeds the machine’s available work area during engraving.
Is it normal to see an error after pressing Stop?
Yes. When Stop is clicked during engraving, the machine reports an error normally because the process was interrupted intentionally.
What is overscan in laser engraving?
Overscan extends movement slightly beyond the engraving area to improve motion smoothness during image engraving and vector filling.
Why does my machine fail during homing?
The controller may continuously detect the limit switch signal after zeroing. Confirm that the XY axis does not remain pressed against the limit switch.
Should I disable overscan completely?
You may turn off the overscan function if it causes soft limit alarms. Alternatively, reposition the design or change coordinates to absolute coordinates.
Can manual movement interrupt engraving accuracy?
Yes. Moving the laser manually during engraving can trigger alarms and affect positioning accuracy.
Does this mean my Ray5 MiniS hardware is damaged?
Usually not. Most engraving alarms are caused by operational actions, software settings, or coordinate configuration issues.
Final Thoughts
Engraving errors or alarms on the Ray5 MiniS are usually related to user operation, software configuration, or limit switch behavior. By following proper usage practices and adjusting settings such as coordinate systems and overscan, most issues can be quickly resolved.
Maintaining correct operation procedures and system calibration ensures stable engraving performance and reduces unnecessary error triggers.
