Wood
The cited source documents conditions for wood. They apply to every wood row on this page.
- Fire:
Utilizing the Air Assist feature will reduce the instance of flare-ups when working with flammable materials such as acrylic and wood.
(Epilog Laser, Reducing Fire Hazards with your Laser, read 2026-09-21) - Fire:
Since most users cut wood and acrylic, these small pieces that fall into the table tray act just like kindling and can ignite and start a fire.
(Epilog Laser, Reducing Fire Hazards with your Laser, read 2026-09-21) - Fire:
But most materials are inherently flammable and can be ignited, which may burn the machine and the surroundings.
(Creality, Creality Falcon2 (12W/22W/40W) User Manual, read 2026-09-21) - Ventilation:
Smoke or smells may be produced during laser engraving and cutting. It is recommended to operate in a well-ventilated environment.
(Creality, Creality Falcon2 (12W/22W/40W) User Manual, read 2026-09-21) - Fire:
It is forbidden to leave it unattended while the machine is working.
(Creality, Creality Falcon2 (12W/22W/40W) User Manual, read 2026-09-21) - Check the composition:
Do not engrave or cut any unknown materials.

Source-documented settings for wood on the LU3-20A/B (20W)
Manufacturer-published reference parameters, not tested by CutChart
Match the machine, material and operation before reading a value. Speed is shown in the source unit and in mm/s, rounded to two decimals. Each row names its publisher and the date we read the document. A field the publisher does not print is shown as not specified; CutChart never fills it in.
No publisher prints air assist, focus and lens for any row below, so every row repeats that field with the name of its own publisher.

These are each publisher's own parameters for its machine and material. CutChart has not run them. Confirm the exact material, focus, air assist and lens with the manufacturer before use.
Read the evidence in context
Our source process explains the checks behind a row. The speed converter changes units; it does not move a setting to another machine. Check power labels with the optical-watt decoder, and read the safety limits before choosing a material.
Common questions
Can I use a row on another machine?
Each row belongs to the stated machine and configuration. A matching wattage or material name does not establish a setting for another machine.
Why are some fields marked not specified?
The publisher’s table prints speed, power and thickness, and sometimes passes, but not air assist, focus or lens. CutChart shows each unprinted field as not specified rather than filling it in.
Why are some combinations absent?
CutChart publishes a row only when its source, exact machine, material, operation and a sourced material-safety statement meet the reference requirements. An absent row is an unknown answer.

When a laser engraver engraves or cuts materials, it casts a high-density laser beam that heats the surface to vaporize materials without burning them. But most materials are inherently flammable and can be ignited, which may burn the machine and the surroundings.
