    Has anyone here converted their Chinese laser to something like wincnc?

    Re: Trouble with new laser

    I have tried speeds between 100 and 400 mm sec, power from 16 to 54% and everywhere in between. You are correct, I was referring to dark gray areas where the laser should be firing but is not. Last...
