    Default Laser Pulse control


    Installed a 15 watt laser on my engraver. Laser works fine in stand-alone mode but cannot control pulse on\off with my controller. I assume the TTL plug-in is what
    controls the pulse? Using a Keyestudio rev 0.9 with GRBL. Any help greatly appreciated!

    This is how I have it hooked up. Shouldn't the input marked laser control, control the laser pulse?Laser Pulse control-laser-control-jpg

    Have you configured grbl to enable laser?

    Do some research. It’s well documented

    You’re welcome. It’s always gratifying to see people making the effort and not just sitting back and wanting to be spoon-fed.

    Thats how I learned. It has paid off, handsomely.

    And FYI, the most powerful diode laser made is ~6.5W, so you were ripped off with your ‘15W’ unit. It’s an over-volted 6W unit. You’ll be lucky if it lasts 200 hours.

    Here, as I’m feeling generous: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Laser-Mode

    Just as a pro tip, I typed ‘grbl laser’ into google and it was the first entry that presented itself.

    Have done my research I know that $32=1 turns laser mode on and 0 turns it off. Have PWM connected to TTL output, but laser still does not turn on and off as it should, could I possibly have a defective controller for the laser?
