Hello,
Do anyone have an answer on this problem.
Under LaserGRBL all work fine, but when I try the same under Lightburn the laser move like it should with the light on but he don’t want to burn.
I have checked following parameters
S-Max value = 1000, $30=1000, $31=0, $32=1
The fire button is set and the value well set to 0,25
Thanks for you attention on this
Regards
My machine is a : Ortur Master 2
There is a section for that machine.
Might give the search a shot, there are lots of discussions that may help…
Good luck 
Thanks a lot

No need to duplicate this post. You can adjust the category. I have made the adjustment for you.
Sorry ! Thenks for you help !
i’ve checked that in Lightburn the max power is set to 255, but you have $30=1000.
You find the parameter in “Edit->device settings/S-value max” mine was 255 while in $30 i had, like you, 1000.
Lightburn Common Grbl Setup, they state:
“You might need to adjust your spindle max RPM value ($30) to match the LightBurn default (1000) or vice versa. The value in LightBurn is called “S-Value Max”, in the Device Settings.”
