    I have Atomstack M50 50W and Black Box ,grbl 1.1
    When running any job, the power is not varying it’s seems to just be full power. I have the jumper relay removed like instructions say and i have the grnd and pwm, 0-10v hooked up, also tried just the grnd and pwm as well and no change. Can anyone tell me what I might be doing wrong?
    These are my settings


    Grbl 1.1g ['$' for help]
    ok
    [VER:1.1g.20181112:CUSTOM]
    [OPT:V,15,128]

    And does your Gcode scale S0-1000 to match?

    0-10v is for VFD spindles, not lasers. Don't connect anything to it, particularly not random connections that could damage your BlackBox

    The s value is the same when I look it up in lightburn setting menu.

    Several options:

    1) CAM settings/setup
    2) toolpath options
    3) review resulting GCODE file

    Also test laser power from the Tool On menu in CONTROL as it takes Grbl Settings into account to help you infer whether the controller got damaged by miswiring, whether the laser is now wired correctly or whether the gcode is not applying the S-word correctly

    Make sure you followed the Lightburn instructions in docs.openbuilds.com too

    I figured it out, I had an extra 0 I didn’t see in S value. Thank you for your help.
