I have a ortur LM3 20W running on a windows 10 machine. l not sure what my firmware is…so anyway, I’m having issues with scorching and burning no matter how many times I adjust my power and/or speeds. It cut fine one day, the next day, not so much. I was looking at my lens and it looks kinda orange…should this be replaced? The first picture is how it used to cut, the second is what I get now. I’m also attaching a photo of the lens that’s installed vs the replacement one they sent. Any comments and/or help will be greatly appreciat
