    $0 – Step Pulse, Microseconds

    Stepper drivers are rated for a certain minimum step pulse length. Check the data sheet or just try some numbers. You want the shortest pulses the stepper drivers can reliably rec… See more

    $1 - Step Idle Delay, Milliseconds

    Every time your steppers complete a motion and come to a stop, Grbl will delay disabling the steppers by this value. OR, you can always keep your axes enabled (powered s… See more

    $2 – Step Port Invert, Mask

    This setting inverts the step pulse signal. By default, a step signal starts at normal-low and goes high upon a step pulse event. After a step pulse time set by $0, the pin resets to lo… See more

    $3 – Direction Port Invert, Mask

    This setting inverts the direction signal for each axis. By default, Grbl assumes that the axes move in a positive direction when the direction pin signal is low, and a negative dir… See more

    What is grbl & how do I use it?
    Please feel free to modify these pages to help keep grbl up-to-date! Grbl is a free, open source, high performance software for controlling the motion of machines that move, that make things, or that make things move, and will run on a straight Arduino. If the maker movement was an industry, Grbl would be the industry standard.
