Hi,
I recently received my 40W laser module, tested it with Luban at is working fine.
When trying to use with Lightburn (with the same setting that was working fine with the 1.6W module) , it keeps going to the bottom left corner and never work in the work area/piece.
Kindly assist with setting I need to adjust in Lightburn
Donāt have the 40W module, but I would assume the info from the wiki should be a good starting point to have it set up:
https://wiki.snapmaker.com/t/lightburn
Thanks, 1st step at least, I got the setting files, but still not working properly, I do not know why the machine keeps going to the most left side and start operating in the same location
OK, I downloaded the (snapmaker-2.0-40v1.lbdev) file from Using Ray / Artisan / 2.0 with LightBurn | Snapmaker Wiki and imported into Lightburn.
Still only cutting and lines tasks are OK. But any engraving task is a total failure.
I checked the Gcode, the difference is that for engraving, Lightburn use relative positioning with code G91, while Luban use absolute positioning withing G90 code.
Was anyone successful in engraving (not cutting) with Lightburn and 40W laser module ?
Yes. I have engraving white laminated MDF 3mm. And after engraving I have cutting it to make a box.
Iām not at home now. I donāt have the settings and files on these computer.
Iām at home Saturday. I post my settings and a file.
I donāt use lightburn but what is the nature of the failure; nothing or overburn?
Just an idea, go into luban (I know your arenāt using it but humor me). Change it to workpiece and center. Then go back to light burn ( I donāt have light burn but Iām computer techy and have seen native programming still have an effect on a machine even when the native program isnāt being used). If light burn has these type settings also, be sure they are the same when creating your gcode
Lightburn has much more settings then Luban. If the settings are correct, it works without any problem.
My first thought is that youssef use user position and not absolute coordinates.
I havenāt delved into lightburn as I just started out. Iām installing my 40w tomorrow and hoping for good results
I have used āAbsolute Coordsā.
But still Lightburn for engraving layers, issue the code using G91 code (Relative coordinates), and for line layers, issue that part of the code using G90 (absolute coordinates)
I attached photos for my current setting as well as the Gcode generated file.
I use this settings
