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

1. 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:

1. Stop the engraving process
2. Reposition the laser correctly
3. 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

3. 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:

1. Change the coordinates to absolute coordinates
2. If the coordinate system is not changed, reduce the pattern
3. Put the pattern in the middle
4. 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

4. 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.

Common Problems and Solutions

Tips for Better Results

• Position designs away from workspace edges
• Use absolute coordinates for larger designs
• Check overscan settings before vector filling
• Test engraving boundaries before starting production jobs
• Keep the machine frame clean and unobstructed
• Monitor homing movement during startup
• Avoid interrupting engraving unless necessary
• Ensure cables and limit switches remain secure

Proper software configuration and operating practices can significantly reduce unnecessary engraving alarms.

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.
