Tried to cut some half-inch and three-quarter-inch plywood. Results, not so good.
Trying to cut 3/4″ plywood from the scrap heap with the standard lens. The test matrix of squares increases power top to bottom and increases speed left to right. The slower settings set fire to everything in the vicinity, which fire was then stoked by the air assist jet. At no speed or power did it actually cut all the way through. I think the problem is depth of focus, and I have a longer focal length lens that should help somewhat.
