If the X-axis or Y-axis motor on your Ray5 laser engraver is moving in the opposite direction than expected, it can lead to incorrect positioning, failed engraving, or even machine errors.
Motor direction is controlled by both hardware wiring and software/firmware signals. To fix a reversed motor, you only need to adjust one of these elements so that they match correctly.
This guide provides three effective methods to correct motor direction, from the easiest (software) to the most advanced (hardware).
Core Principle
Motor rotation direction is determined by:
Motor wiring sequence → Physical wiring defines the default rotation
Direction control signal → Software/firmware instructs the driver on movement direction
To fix a reversed motor, you align the control signal with the wiring direction.
If software settings are insufficient, modify firmware parameters directly.
Using G-code commands (via LightBurn or LaserGRBL):
Connect the machine to your computer
Open the Console / Terminal window
Use the following GRBL parameter:
$3 – Direction invert setting
How it works:
Each axis direction is controlled by a binary value
Setting the parameter to true inverts direction
Examples:
Reverse X-axis → set X direction invert to true
Reverse Y-axis → set Y direction invert to true
⚠️ Tip: If the motor is reversed, simply toggle the setting (true/false) until the direction is correct.
Save the changes
Test using jog controls
Step 3: Hardware Adjustment (Physical Solution)
If software and firmware adjustments do not resolve the issue:
Reversing Motor Wiring
Power off the machine completely
Locate the motor cable of the reversed axis
Swap any one pair of wires:
A+ ↔ A−
or B+ ↔ B−
This will physically reverse the motor rotation direction.
Reconnect and power on the machine
Test the axis movement
Important Notes
Always try software settings first before modifying hardware
Ensure the machine is powered off before any wiring changes
Avoid changing both software and hardware simultaneously—adjust one at a time
Conclusion
Motor reversal on the Ray5 is a common but easily fixable issue. In most cases, it can be resolved through simple software configuration changes. For persistent cases, firmware or hardware adjustments provide a reliable solution.
By following the steps outlined above, you can quickly restore correct axis movement and ensure accurate engraving performance.
Movement Protection Triggered on Ray5 10W and Ray5 5W
The flame sensor and motion sensor are important safety features designed to protect your engraving process. However, they can sometimes be triggered unintentionally due to environmental factors, incorrect settings, or hardware issues. This guide will help you identify and resolve common alarm problems.
Flame Sensor Alarm
The flame sensor can be easily triggered. When it is activated, the LightBurn console will display Alarm 3. This can happen for several reasons, including ignition during use, strong light exposure, incorrect settings, short circuits, or even sensor damage.
To avoid unnecessary alarms, it is important to maintain a proper working environment. Avoid open flames during engraving. If an open flame occurs, reduce the laser power immediately to prevent triggering the sensor.
Environmental lighting also plays a role. The engraving machine should be placed in a normal indoor environment and kept away from strong light sources such as flashlights or direct sunlight, as these can interfere with the sensor.
If the flame sensor is still triggering, you can adjust its sensitivity. Open LightBurn or LaserGrbl, connect your machine via USB, and enter the following command in the control panel:
$42=1300
This command lowers the flame sensor trigger threshold. If the issue continues, you can further reduce the value until the sensor behaves normally.
In some cases, the issue may be caused by a hardware contact. If the flame sensor is triggered at the beginning of engraving, check whether the sensor’s metal pins are touching the metal casing. The flame sensor is a black cylindrical probe located at the back of the RAY5 control box. Carefully adjust its position to prevent contact.
If necessary, you can temporarily disable the flame sensor by entering:
$38=0
To enable it again, use:
$38=1
Motion Sensor Alarm
The motion sensor is designed to detect unexpected movement during operation. However, it may also trigger due to machine instability, incorrect settings, or sensor issues.
Make sure your engraving machine is placed on a stable and level surface. Any vibration or movement during operation can cause the motion sensor to activate.
If the sensor is too sensitive, you can adjust its trigger threshold through software. Open LightBurn or LaserGrbl, connect your machine via USB, and enter the following commands:
$40=200 $41=40
These commands reduce the sensitivity of the motion sensor and help prevent false alarms.
If the motion sensor continues to trigger at the start of engraving, it may indicate a hardware issue. In this case, you can disable the motion sensor by entering:
$39=0
To turn it back on, simply send:
$39=1
Conclusion
Flame sensor and motion sensor alarms are usually caused by environmental interference, overly sensitive settings, or hardware-related issues. Most problems can be resolved by adjusting settings, improving the working environment, or checking hardware connections.
