r/LightBurn

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.

I’ve been using my laptop with my laser everyday with no problems but today I went to connect the laptop to the laser and the USB port isn’t in the list next to Device in the laser control window. I reinstalled the driver but that didn’t help. How do get my computer and laser communicating again?

What would cause my laser module to move reliably by set distance, but not by continuous jog? I’ve been having crazy problems with my laser this week. It’s an xtool D1 with extension rails, controlled by a Devil1 controller. I’ve had some projects ruined because my module will randomly not move to the correct location. In my troubleshooting I’ve discovered that I can reliably move the module anywhere in the work area by using the move buttons set to a certain distance, but if I try to use continuous jog the module will move some distance and then just stop. When it stops I can switch off continuous jog and it will move properly by set distance. What would cause my module to move reliably by fixed distance but not by continuous jog?
