Tutorial of installing the LU3-20A Laser Module
on Ortur Laser Engraver

The 20W laser module is not only upgraded in terms of power, it applies advanced COS technology, which presses four 5W diodes into an extremely fine beam and maintains a powerful energy, enabling speeds of up to 20,000mm/min and perfect single cuts. In addition, it can also achieve colorful engraving effects on stainless steel, so you are no longer limited to black and white creations.

It is important to note that the 20W laser module is compatible with all of Ortur's laser engraving machines, but don't worry, the installation of the 20W laser module is very simple. This article will explain in detail how to install the 20W laser module on other laser engraving machines and there will be a video tutorial, so be sure to read it carefully!
