    Z AXIS NOT RESPONDING TO GCODE COMMANDS

    Using GRBL controller, everything works right when I send my files except the z axis, it simply does not respond, Manual commands work perfectly as well the axis controls by
    keyboard. I am attaching the beginning of a file, maybe someone can see something I don't, thanx

    T1 M6
    X-70.877 Y110.684
    G01 Z-2. F150
    X-70.842 F450

    The x and y command responds, the z command does not.

    The x and y command responds, the z command does not.

    Is the z axis setup for the right pins and ports (check)
    Is the drive working (check, swap with a working axis.... This will also test the stepper motor)

    Z axis works fine with manual control on keyboard and if I send a typed command in GRBL controller, does not respond to commands generated with artcam or abviewer? Just can't figure it out!

    Re: Z AXIS NOT RESPONDING TO GCODE COMMANDS

    Any change if:
    (rapid movement)

    X-70.877 Y110.684
    Z-2. F150
    X-70.842 F450

    OR

    G00 X-70.877 Y110.684
    G01 Z-2. F150
    G01 X-70.842 F450

    Remove everything else in this code, just run those lines.
