Demystifying the Lightburn GRAYSCALE Image Mode
HTML-код
- Опубликовано: 28 сен 2023
- In this video we are going to do a general overview of how the Lightburn Grayscale Image Mode functions. Including the important distinction between the Grayscale mode and other dithering options. This video is a overview intro to a series I am going to do on using this mode. This one is NOT a tutorial.
I focus more on how the Grayscale mode relates to engraving photographs using diode lasers because that is where I see the most confusion on the topic. However there is a small section on how this applies to CO2 lasers. Again, I will do full videos on each of those topics in the future.

Please don't ever stop making videos! You explain things in ways that even dummies like me can pick up, understand, and put into practice. I thank you for that.
I constantly learn new things on these machines thanks to videos like this. Awesome job!!
You knocked it out of the park with this explanation. Appreciate you.
Appreciate it! Thank you.
This will help me quit my dithering and get to it.
Thanks for this video...first one I've seen on this topic and very well done.
Thank you appreciate it!
This was very helpful, thanks. I'd love to see a video on using Lightburn's "step-down" mode, i.e., when cutting acrylic. I'm having a hard time getting it to work.
Thank you for that.... I wish it touched on fiber more, Having a time getting get good contrast or detail on stainless steel with my 60w MOPA. Your power explanation changed how i was thinking about it, Going to experiment now.
Great explanations! Thank you.
Great video and very informative. Actually the only and best one I’ve seen on this topic. I’ve been trying to understand the grayscale mode for quite some time. In your video you stated you tried it with your fiber laser, I’ve been trying to get good images on my fiber laser and just can’t. Any suggestions ? Image processing etc.
Great video. Very Helpful. Thank you.
Thank you for watching!
Thank you , this is so helpful
great video !!
Very useful, many thanks.
Thank you for watching.
Thank you for this video I have been told to use gray scale for my images and it just burns the wood with no detail this explains a lot
Thanks for watching hope it helps get that resolved!
Great video
Thank you
Hope you will make a video in detail for CO2 specifically engraving an image detailing its settings using Lightburn 🙏🏼
Yes I can do that.
Perfect😮
Thank you. Wonder why i would then use a mode other than grayscale? If grayscale gives best result.
Hello Justin,
do you recommend the settings used at 3:02 for getting sharp results for that specific picture or are those just place-holder numbers?
Hay awesome thanks. But I have a question if I use a diode laser Using gray scale, could I engraved multiple times to get a 3-D effect or depth?
Awesome video. When adjusting in Lightburn (In Grayscale), would you suggest to make Contrast less and White more? Or other? thanks.
What I like to do is run a small section of the image, maybe 2" x 2", without doing any edits to see what Im working with. Grayscale mode results can vary wildly based on the material. Once I gauge what it looks like I start tweaking from there. Adding contrast is usually preferable. If its too dark or too light I mess with the gamma correction first. That usually helps out the most in those instances!
Great explanation, i noticed at the end of the video, you Said some modules are compatible some arent. When i try to use grayscale my laser doesnt engrave at a continues speed, it slows down in some áreas and it speeds up on other, is that the compatibility issues you are talking about? If not is there a workaround for this issue? I would like to engrave at a contínuos speed like i do in other engraving options (dithering) using grayscale.
I use lightburn latest version with LaserPecker lx1 with the 10w module. Thanks in advance
Do you have a specific wood type for doing a 3D engraving with a Co2 laser? Mine is a 80 watt. I’ve heard Alder and Cedar are great types.
@justinlaser So I have the ortur LM3 with the 20W laser module. I did a test on matte black painted white tile and the sweet spot for power to get all the paint off is 25% max and min power I set to like 10% at 6000/mm speed. When I try to do the image in grayscale mode the laser continually fires and burns the paint off at the highest power instead of shading like it's supposed to. Any tips? Should I set the max power higher or the min power lower? I'm stumped at this point lol. If anybody else has this issue please let me know. I get great work out of dithering with stucki and jarvis but grayscale doesn't work right now.
Great vid. Hopefully, I can get similar results from my 10W UV. What have you found that works the best in turning a picture into a height map?
Ive been trying to learn that practice on and off for a few months and havent come across anything I really like yet. Every tutorial suggests a completely different software and process.
Is the principle the same if I’m using a 30w fiber laser? I’m wanting to place a photo image on a Black medal tumbler. Thank you
I know what it said, but I use my diode for variable depth all the time. It isn't fast, but it works fine.
Do you use the 40W? I have a 40W S1 xtool and will be attempting my first 3d illusion engraving.
If importing an image to engrave tile processed by imagr do you choose grayscale? How do you know what settings to use?
If you processed in IMAGR first you will never use Grayscale since it has already been dithered. I usually start with Jarvis or Stucki since they are the best in my opinion. From there you have to run tests to see what you like.
Thank you for the video, I am confused about one thing. Why do you set max power to 50% and not 100% or 80%.. Thank you again
100% would most likely be overkill for the speed Im running the project. For some stuff, especially photo engraving, slower speed and lower power works better.
Would a Fiber Mopa 80watt cut 3d in metal with depth mapped images in greyscale?
Yes! The image mode is called "3D Sliced" when you use fiber laser in Lightburn. The settings look a little different but its the same idea.
Could you make a video on how to make depth map images out of 2D AI created images?
Man Im still figuring that out myself. Keep running into dead ends with the available apps and need to learn more 3D skills.
Good video, very quiet though for future knowledge
Thanks for the heads up I must have forgot one of my normal audio settings somewhere.
@@justinlaser was all good was just watching other stuff and noticed the audio drop, probably me just being old! Lol
Can I do it that on atomstack x20 pro
Yes if you can use Lightburn
@@justinlaser ya i can ,
But The image is duplicating in some parts of the adonized business card, and I don't know if it's due to the speed, power, or scanning angle , thanks
@@justinlaser
Or horizontal lines appear along the image.
