How to Fix Engraving Lag on Nano Duo

Nano Duo is designed as a high-speed engraving system. However, engraving lag may occur when the data transmission speed from the software to the machine cannot keep up with the engraving speed. This can result in delays, pauses, or uneven engraving performance.

To ensure smooth operation, it is important to optimize data transmission efficiency and reduce communication bottlenecks. One of the most effective solutions is enabling G-code clustering within the software.

It is important to note that engraving via SD card does not rely on real-time data transmission from the computer. As a result, this method does not experience lag and is recommended for high-speed or complex engraving tasks.

1. LightBurn

Click the button in the top menu bar, enable the Enable GCode Clustering option, and click OK.

2. LaserBurn PC

Click the button in the top menu bar to open the Machine Settings interface, enable the Enable GCode Clustering option, and click Save.

Conclusion

Engraving lag on Nano Duo is typically caused by limitations in real-time data transmission rather than hardware performance issues. By enabling G-code clustering in supported software such as LightBurn and LaserBurn PC, users can significantly improve data flow efficiency and reduce or eliminate lag.

For the best results, it is also recommended to use SD card engraving when working with high-speed or complex designs, as it ensures stable and uninterrupted operation. By applying these optimizations, users can achieve smoother engraving performance and more consistent output quality.
