I have Creality Falcon 2 Pro 40w. As a beginner, I had no idea how that laser or Lightburn software works.
First I did try to burn 3mm ply, but my laser couldnt cut it, just left little mark on it. After a few ours adjusting, i found in settings "S- value max". That value was (default?) something like 3,4, I dont remember
I did up it 200, it seem to help, then 400 then 500.
Now my laser burn much better, but i have no idea what is that “S- value” and how high i dare to go??
Could it harm the laser head if i go too high?
Could somebody tell me what is it, and how i get to learn to use Lightburn software. There are so so many value setting which i have no glue…
If you have an 8 bit controller, then there isn’t much point to going above 255, a 16 bit controller will give finer detail. However, IMHO I’ve never seen material that will take a 256 different values to produce 256 shades of gray making anything above 255 rather useless. If you stick with the documented values of 1000, it will work fine. Using 1000, with a 32 bit controller gives you finer control.
S-Value Max, is actually the maximum spindle speed, it’s related to minimum spindle speed $30, whereas the controller will generate the proper pwm for the expected spindle speed range.
With a laser, there is no range of speeds, so you want the widest possible pwm control, leaving the suggested 1000 or 255 for S-Value Max. The controller has to know how to handle the generated code, so it references both $30 (minimum spindle speed) and $31 (maximum spindle speed).
As @fins suggested, use what’s recommended in the documentation. You can’t get better greater than 100% pwm, no matter how you fiddle with the numbers. S-value Max tells Lightburn the range and $30 tells the controller the, hopefully, same range.
Hope this make sense…

Thank you, it makes sense!!
Now I understand much more, after read about configuration.
