Guys, I’m having some terrible problems getting through a 19mm 1x4, (3/4"x3.whatever") solid wood. it’s taking 3 passes at 17ma and one side had to be forced out. I think my mirrors are dirty.
(humor me, I’m drunk)
Getting serious now, this was done with a 38.1mm focal lens. First pic is a little charred because I slowed it down to 2mm/s and 2 passes. Second pic is 4mm/s and 3-4 passes. (totally forget if 3 or 4 because I was on the phone, will duplicate tomorrow.) 17ma is about as high as I ever want to go, but after a few passes, I would have thought the second one would be charred more.
Don, it’s safe to say my replacement tube and new power supply are working correctly.
