I have a OMTech 130W laser. I’m trying to engrave an image on a piece of mirror acrylic that’s the size 35” x 23”. The issue I’m having is when I make my adjustments to the image so it looks correct under the “preview” section, then I go to scale up the image to the correct size and then I click “preview” again, the preview runs almost completely black. I’ve tried so many adjustment variations such as contrast, gamma , brightness, enhance radius, all the image types, DPI, and nothing works when it’s blown up to that size. Ive also messed around with the trace image feature and it doesn’t give the effect I’m looking for. What is weird is whenever I try the image type “Greyscale”, the preview comes out perfect, BUT when I go to engrave it looks nothing like the preview and the engraving turns out very dark. I’ve even tried to adjust the size in Adobe Illustrator and then export/import to Lightburn and I’m still having these issues. It seems like no matter what I do, I cant engrave a picture that large onto acrylic, or any material for that matter. Any suggestions are greatly appreciated. I would say don’t bother to suggest any setting changes to the above mentioned because trust me Ive already tried nearly every variation. I feel like this should be possible but at this point I don’t know.
