Focus the diod laser

I can´t focus the diod J-tech laser
beacause every time I start the fire button
it start burning , even if I have set the procent to 0,5
What do I do wrong, or forget

Have a review of this to see if you have things set up correctly.

Additionally, make sure the $30 in your settings matches the ‘s-value max’ parameter in the Device Settings in LightBurn as this can cause this issue as well.

The J-Tech lasers should also have a potentiometer on them to turn the power down even further. See focusing method 2 here:
