LightBurn Tips - Fixing GRBL Intensity Problems!

In this episode, we will show you how to properly set the intensity values inside of LightBurn to match those of GRBL.  As in the example my GRBL based laser was only outputting 1/4 of the power when set to 100% (i.e. S1000).  At first we though it to be hardware issue however doing some digging we found the S-Max Value and it was set to 255 approximately 25% of the actual max value (i.e. $30=1000) which GRBL understood to be the maximum.  So if your having issues with your GRBL based laser under performing this, is the first place I would suggest looking!
