FAQs
How do I switch power modes?
Easily adjust power with a one-touch switch on the module.
Can I switch power while in use?
Yes, but we don’t recommend switching power modes during operation.
Which engraving machines are compatible with the LU3-40A laser module?
The LU3-40A works with the OLM3 and OLM3 LE models via OUC2.0.
Is the LU3-40A laser module compatible with other accessories?
Yes, it’s compatible with all current Ortur accessories. We recommend pairing it with an air pump and the LEP 1.0 to protect your work surface. Since the 40W laser generates more heat and dust, an air pump helps dissipate heat, clear dust, protect the lens, and prevent burn marks.
What other accessories do users frequently order?
- YRC 1.0 – Ideal for engraving cylindrical objects like tumblers, Christmas ornaments, and rings.
- Extension Kits – Expands the working area for engraving or cutting larger materials.
- Enclosure 2.0 & Smoke Purifier 1.0 – Recommended for indoor use to maintain clean air quality.
How does the power switch from 20W to 40W?
The power adjustment is controlled by an internal switch. In 20W mode, four diodes are activated, while in 40W mode, all eight diodes emit light, doubling the power output.
