deep cutting wood

I have not seen this question and am hoping that someone might be able to provide an answer.

A client wants me to laser a sign made of wood (California redwood). He has had signs in the past made using a router and has not been pleased. However he does like the "deep" grooves that the routers make.

In the past I have made deep laser cuts using a series of passes. Unfortunately in some cases the surrounding surface wood was scorched.

Am I better off reducing the number of passes by increasing the power and reducing the speed, or am I better off using the normal settings and making more passes? Also, will masking the top of the wood help or hinder the process?

laser cutter no good to deep cutting wood.But in my opinion,you can try to use high pressure air compressor: provides the compressed air with greater pressure than the air pump so as to prevent flammable material burning on wood laser cutting machine.

Using the engraving function, high pressure air and high power I can carve 6mm on our 150W machine when doing signs, masking the surface can help, but you can get rid of a lot of surface charring by putting the wooden piece under running water ( after its cut ) and using a soft brush to loosen any debris/soot

From my experience of using Argon gas, that could be another solution for you. But you will need 90% close chamber for better effect.
When I weld or cut, Argon gas shield around the object to prevent from oxidation. I am not so sure with wood work, never tried it before. Just sharing my thought.

Sounds like it might have been successful. BTW I wouldnt normally expect the oil to penetrate to the middle of the wood - just a little bit into the surface.
