It lets users preview the engraving area before starting the job, minimizing material waste and errors. This guide walks you through enabling Framing Mode in LightBurn—just activate the laser fire button, set framing power to 2%, and you're ready to frame with precision. Perfect your setup and avoid costly mistakes with this simple yet crucial step in the engraving process.
Longer laser engravers like Ray5 and B1 series can create brilliant multicolor engravings on metal, starting from just 10W of power. Using LightBurn's Material Test, users can easily identify the best settings to unlock vibrant shades. Even with lower-power lasers, up to 90 distinct colors are possible, making metal engraving both creative and accessible. Learn how to test, tweak, and master color engraving with your Longer machine.
Proper cooling is critical for maintaining laser performance and preventing damage to your laser module. The Longer B1 cooling fan continuously removes heat generated during engraving and cutting operations. Over time, smoke and dust can accumulate inside the fan, reducing airflow and cooling efficiency. In some cases, prolonged use may cause the fan to stop working entirely, making cleaning or replacement necessary.
The Longer B1 fan recovery and replacement process restores cooling performance for the laser module used in Longer B1 series laser engravers. It involves cleaning accumulated dust and smoke debris from the fan or replacing a damaged fan with the correct specifications.
The cooling fan serves an important role inside the laser module:
This maintenance procedure is intended for:

| Question/Issue | Explanation | Recommendation |
|---|---|---|
| Fan becomes noisy | Dust accumulation may affect operation | Clean fan thoroughly |
| Cooling seems weak | Smoke and debris may restrict airflow | Inspect laser module |
| Fan stopped spinning | Prolonged use may lead to failure | Replace fan immediately |
| Laser module becomes hot | Cooling performance may be reduced | Check fan condition |
| Unsure which fan to buy | Replacement specifications are defined | Use 60 mm × 60 mm, 24V, 0.40A |
No. The source procedure specifically applies to:
Cleaning restores cooling effectiveness, which helps maintain stable laser operation.
The original procedure only mentions disconnecting and reconnecting existing components.
Follow official product specifications.
The source does not specify a replacement interval. Replacement is necessary if the fan becomes damaged or stops functioning.
Users can follow the documented procedure carefully. Handle internal components gently during disassembly.
Replacement fan specification:
Smoke and wood dust generated during engraving can enter the cooling system over time.
The Longer B1 fan replacement and recovery process addresses an important maintenance need: preserving proper laser module cooling. Dust and smoke accumulation can gradually reduce cooling performance, while a failed fan can potentially lead to overheating issues.
Users who frequently engrave materials that produce smoke or debris should consider regular inspection and maintenance. Key reminders include:
Maintaining proper airflow helps support reliable operation of Longer B1 20W, 30W, and 40W laser engravers.
Longer Ray5 is an innovative and powerful laser engraver, available in 5w, 10w, 20w and now even 30w versions. Depending on the type of laser module with which it is equipped, Longer Ray5 can perform various types of processing on various materials, but one feature is always in common, namely the absolute accuracy in the execution of the processes.
Sometimes, however, strange effects can occur, similar to those present in the image below; in these cases, it is necessary to fine-tune your machine, so as to obtain maximum performance.
Usually, this problem is due to a poor installation of the belts and eccentric wheels, so it is necessary to proceed with a more accurate installation.
First, completely disconnect all the connectors of the Longer Ray5, then remove the connection cable.
Once this is done, squeeze the belt as shown in the figure. The belt must be hard, resistant to pressure. If, on the other hand, it is soft, then it is necessary to put it under tension.
In order to tension the belt, unscrew the T-nut as shown in the figure, then pull the belt with your hand. Keeping the strap under tension with your hand, continue to pull and simultaneously screw the T-nut tightly to secure the strap in place.
Repeat the belt tension operation in the same way for the other side of the Longer Ray5 frame.
Finally, make sure that the sync wheel is perfectly in line with the belt. To do this, unscrew the Sync Wheel latch as shown in the figure, then put the Sync Wheel in line and secure the latch.
At this point, check the wheel eccentrics as well. The wheels equipped with an eccentric nut are the lower ones. With your finger, try to rotate the wheel; If but wheel slip, you need to tighten the eccentric nut of the wheel.
Gradually tighten the eccentric nut of the wheel, gradually checking that the wheel no longer slips. Do not tighten the eccentric nut too much, but stop as soon as the wheel no longer slips.
Do these for both the left and right sides of Longer Ray5.
At this point, the installation has been successfully completed for the Y-axis of Longer Ray5. However, you also need to check the status of the X-axis, which is the axis that moves the laser module.
Following the steps above, first check the X-axis belt, tightening it if necessary. After that, also check the eccentric nut of the wheel, as shown above.
Once the tuning has been successfully completed for both the Y-axis and the X-axis, Longer Ray5 will have correctly acquired its reliability and accuracy, and therefore it will be possible to obtain precise and dimensionally correct engravings and cuts for a long time.
Periodically, always check the belts and eccentric nuts, so as to keep the reliability of Longer Ray5 constant over time.
