If the machine suddenly stops during engraving, the main causes are:

1. Data Loss

If connected via USB, a loose USB port connection or a damaged cable may cause the connection to be lost. Replace the USB cable if necessary.

2. Machine Alarm

During engraving, alarms can be triggered by vibration, tilting, or other unsafe conditions. When an alarm occurs, the red indicator light will turn on and the engraving will stop.

 Once the alarm is cleared, the machine can resume engraving normally.

If the alarm does not clear automatically, connect the machine to a computer, open LightBurn or LaserBurn, and enter $X in the console to reset the alarm.

Troubleshooting:

1. Network
Check whether the Nano Pro and the computer are on the same network. If they are not, IP connection will fail. You can configure the network through the screen or the mobile app.

2. Device in Use

Here, we’ll explore how this engraver cutter laser model achieves impressive portability while maintaining powerful performance, making it ideal for everything from wood engraving to intricate stone engraving.

1. Lightweight Design of the Nano Series

From the outset, the Nano series was designed as a portable laser engraver, with a focus on a streamlined layout that reduces unnecessary components and weight without compromising functionality. By integrating components like the main board, laser head, lenses, sensors, and galvanometer motors into a compact structure, the Nano series achieves the power of a full-sized laser cutter and engraver in a much smaller, lighter form. 

Constructed from lightweight but high-strength aluminum alloy, this portable engraver prioritizes durability alongside weight reduction, creating an engraving machine for jewelry, glass, wood, and other materials. At a fraction of the weight of traditional frame lasers, the Nano series still provides outstanding power and precision, earning it a place among the best laser engravers for portability without sacrificing quality.

2. High Performance Capabilities of the Nano Series
The high-performance aspects of the Nano series cover several key features:

(1) Laser Power
Equipped with high-power imported diode laser heads, the Nano series laser cutter offers significant power advantages. For example, the Nano Pro incorporates two high-performance laser chips, reaching up to 12W, providing a 20% increase over the more common 10W laser heads. This power boost enables the Nano Pro to cut wood up to 10mm thick and engrave color on stainless steel, making it a top choice as a laser engraver for wood and other materials.

(2) Engraving Speed
Using a high-speed galvo system, the Nano series enables engraving speeds that exceed those of traditional frame-based machines. Additionally, its unique distortion correction algorithm ensures precise laser beam positioning, making it highly effective for detailed wood engraving, glass engraving, and stone engraving applications. With speeds up to 5000mm/s and a preview speed of 32000mm/s, the Nano series stands out as a fast, reliable handheld laser engraver.

(3) Safety Measures 
Prioritizing user safety, the Nano series laser engraver includes temperature sensors and accelerometers. The laser engraver automatically shuts off if it detects sudden tilting or drops, providing peace of mind during operation. Additionally, the protective enclosure, made from a flame-resistant material, intercepts over 99.5% of blue light, protecting users’ eyes from potential harm (although proper laser goggles are always recommended during operation).

Conclusion
Combining portability, high performance, and safety, the Nano series is truly the best laser engraver for users who need a reliable, portable laser engraver and cutter for various materials and applications. Whether you’re setting up a little machine shop store or crafting intricate designs at home, the Nano series is the versatile, powerful solution you’ve been looking for.

Longer Nano Series (Longer Nano Pro 12W and Nano 6W) is a powerful and versatile laser engraver, as it allows you to engrave multiple types of materials anywhere thanks to its compact size. Adopting the latest technologies, it allows it to be used in a practical and simple way, and for this reason all its connections are made via USB Type-C cables. Type-C cables allow a stable and secure connection, but at the same time they are easily usable cables even without particular problems; however, not all Type-C cables are created equal, and the differences are often not easily recognizable. Therefore, if one of the Type-C cables in your Longer Nano needs to be replaced as a result of loss or damage, you should carefully choose a Type-C cable that does not cause any problems.

USB Type-C cables have become a common standard for charging and data transfer in many modern devices, from mobile phones to laptops. However, their specifications can vary greatly, affecting performance and type of use. One of the most important aspects to consider in Type-C cables is their voltage and current capacity. Some cables only support 5V and a few milliamps (mA), making them only suitable for charging low-power devices such as earbuds. Other cables, on the other hand, can support much higher currents, up to 5A, allowing fast charging of devices such as smartphones and laptops. In addition, some cables are designed to support higher voltages of up to 20V, which is essential for fast charging. Fast charging is a feature of Type-C cables that adopt Power Delivery (PD) technology, which can provide up to 240W of power, allowing you to quickly charge devices such as laptops and tablets. Due to the great power, it is important that the cable is certified for fast charging, to avoid compatibility and safety issues.

When a device is connected to a PD-compatible power source, these two communicate with each other to determine the amount of power needed. Then both the voltage and current are adjusted according to the needs of the device, providing exactly the amount of energy required. PD technology supports various voltage levels, ranging from 5V up to 20V, in intermediate increments of 9V and 15V, allowing it to adapt to different power needs.

Another issue to keep in mind is that some cables are designed for charging only and do not support data transfer. Only cables certified to the USB 3.1 Gen 2 standard can transfer data at very high speeds of up to 10Gbps, so if you need to transfer large amounts of data, it's essential to choose a cable that supports fast transfer speeds.

So, based on these premises, when it is necessary to replace one of the Type-C cables of Longer Nano it is good to choose a cable compatible with PD and USB 3.1, so as to be sure that everything works at its best. When choosing, keep in mind that thicker cables can support higher currents without overheating, they also use better materials for connectors and internal wires, reducing resistance and improving the efficiency of charging and data transfer. Certifications are also important, so a cable from a certified brand, which ensures full compatibility with PD and USB 3.1 can be a good choice. Usually cables equipped with these characteristics also integrate a display that indicates the instantaneous power supplied, and which can therefore guarantee their full compatibility with the assigned task.
