I was watching a series of videos on Youtube in preparation for a class on a Laser Engraver at NoVA Labs tomorrow. The guy was talking about settup cutting speed, power and stuff. He got to 'Through Power' and said he didn't know what it does. I googled it and the all-knowing internet says that it's a pause before the head starts to move so that the laser has time to initially drill through the material. That initial pause made me think of oxy-acetylene cutting steel where you have to pause before starting your cut to let the torch cut through the material. Is that what through power is?
Then I wondered if you could use a laser engraver to cut steel by piping oxygen into the head. The video showed that you can blow air through the nozzle to blow away smoke and particulates. Could you substitute O2 to facilitate cutting? I don't plan to do that but...inquiring minds...
thanks
