Any chance you could add spindle speed control #10

I would like to use GRBL with a laser engraver. I would use the spindle speed control to adjust the laser intensity for engraving pictures.

Well it is possible... how would you adjust the laser intensity.. with voltage ? if so what range

Yeah, the driver uses 0-10v. But even if I could get the 0-5v from the Arduino that would be fine as I could use a BC547 to get me to 0-10v
