Is there any negative to setting the lasers power too low for a material? I mean, of course it won’t cut/engrave if the power level isn’t high enough, but anything else?
For example, i’ve been messing with cardboard, and noticed a distinct burnt cardboard smell and have been adjusting power/speed to minimize it. I noticed the lower power seems to smell worse and makes me wonder if perhaps its actually burning rather than vaporizing?
Could just be placebo though.
