Hi everybody,
I want to engrave a picture and some text on wood, but I’m already having trouble with Luban.
I tried to load the SVG file, but it didn’t work. So I thought maybe the file was too big. When I export it as a PNG and load it in Luban, the resolution decreases significantly.
Is this just an issue with the Luban display, or will it be engraved like this?
Also, what is the maximum file size for a Luban SVG? This one was 2,879 kB and I couldn’t load it.
So,
I tried to engrave it, but it didn’t work.
Since I was using plywood, I used the standard Luban settings. But it seems to me that the fill interval is too high. When I reduce it to 0.05, the preview looks much better. The work speed is 6000 mm/min. Is this normal? It seems really high to me and I wonder if this is the reason it didn’t engrave.
Also, how can I find the right power setting? If it’s too high, I think it could burn. Is there a ratio between power and speed?
Which laser are you using? blue 1.6, 10, 20 or 40W? Or the IR 2W?
My recommendation: Create a test pattern (can be done by now directly in Luban!), where you use speed and laser power as parameters to check. See which settings work best on your specific wood.
For the line spacing: Select your laser here: Snapmaker Laser Modules Comparison – Snapmaker EU and look for the line “Laser Spot Dimensions”. This gives you an idea what a realistic line spacing is. Going smaller than the smallest dimension of the laser spot will cause lines to overlap, resulting in inconsistent engravings. Going larger than the largest dimension will cause gaps in the picture. When you do the test pattern, use the line spacing you intend to use for the image.
The line spacing will govern the resolution of the image. So, from that standpoint, the 2W IR would be the best laser, having 0.03x0.03 mm laser spot, but unfortunately the IR laser is very bad on wood. You’ll need one of the blue laser modules.
Hi Hauke,
Thanks for the quick reply.
I have the 10W laser.
I will try that with the pattern in luban to make some quick adjustments. And hope I will come quick to a good result. Unfortunately I don’t have a lot of time for this project. I let your know if this works.
You must upload the file in JPG format to Luban.
SVG works well, no need to go to inferior bitmap formats.
