Try to split the photo down the middle, either horizontally or vertically, so that each half has a similar histogram (if this is even possible with the photo). That will help mitigate the difference in brightness. For example, if it's an outdoor scene with ground on the bottom and sky at the top, split it down the middle from top to bottom... if you have roughly equal parts sky and ground in both pieces, it should help.

Toni Most machines will not handle wood of that size unless they have a pass through feature or unless they have a front door which can be opened and by-passed. Opening and by-passing the front door is more common and you should be able to find somebody to do the job as you describe. There are larger lasers out there which can easily do the job but not a lot of them.

Not sure what's causing it, but if you needed it yesterday, you might consider engraving it and filling with oil based white paint to even it out. Not the best answer, but if you're in a pinch, you have to improvise.

Roy; When you say 1/8" in 'front' of where the laser strikes the surface.. Which 'in front" do you mean? The laser can travel in four directions, but the air direction from the nozzle is fixed.. Or, do you mean 'in front' meaning towards the front of the machine and not in front of the beam/kerf direction. Is there a tech sheet to explain the correct position?

David, I am at a total loss for words. You are an unbelievably talented and skilled person.

IMO one should never have flaming , even cutting thick stuff if you got enough pressure and flow in respect of air assist. In 10+ years with 3 models of laser currently running 6 , we have had flaming one time and that was when our main compressor broke and we used an inadequate one. The exhaust system itself , whether working or not has never a factor in our setup , I could however forsee that perhaps a very strong one could concievably...

That is unbelievably awesome. That could be the smallest toilet on earth.

Ron, Unless there is some specific reason to engrave on the front, I most always reverse-engrave on the back. I think it's more professional looking, plus I just don't like a 'cut-up' surface on the front. One exception may be if you have a compound picture--- There have been a few times where I've engraved on both sides with very striking results. For example, a car in the foreground (front) and mountains in the...
