Humidity/cut parameters

qa

#1

Yet another totally new to laser cutters question.

If I buy wood on a 30% humidity day and a 80% humidity day can I expect a lot of variance in the cut and engraving settings?


#2

I would imagine so. Water can absorb alot of energy.


#3

Kind of a loaded question.
You’re talking about RH (relative humidity) that is relative to temperature and only providing half the info.
Wood is measured in MC (Moisture Content).

Have a look at this paper.

It would stand to reason that wood with a higher content of moisture would require more power to do the same work than equal wood with a lower moisture content.
