me too. I've got a framed piece of plywood with a charred hole in the middle burned 1/4" around. I started the laser and held down the "test" button expecting it to run some sort of test pattern like a inkjet printer does. I put a caption on the little framed board to ALWAYS read the manual BEFORE testing". It never pays to test first.
lol I would have mine framed as well (great idea btw) if it wan't for the fact that its the wall! I had the head sitting sideways at the time of powering up. So now there's a charred hole on the wall
