    HI SETTING UP EMC2 AND HAVE GOTTEN ALL MOTORS RUNNING AND VELOCITY / ACCELARATION SET. HOW
    WOULD YOU GO ABOUT FINE TUNING THINGS FOR ACCURACY AND REPEATABILITY. I WAS RUNNING MACH
    AND YOU WERE ABLE TO DO ACCURACY/REPEATABILITY
    TUNING. I HAVN'T FOUND ANYTHING IN EMC OR DOCS
    SPECIFICLY POINTING THESE SETTINGS ?

    ALSO MAY FIGURE THIS OUT BUT HOMING IS GOING THE
    WRONG DIRECTION REGARDLESS OF TABLE SIZE HOME POSITION SETTINGS. HAVE PIN SET BOTH LIMIT + HOME ?

    SO FAR SO GOOD
    THANKS TO ALL.

    Homing direction is controlled by the velocity value sign. If you want to home in the other direction put a minus sign in front of your homing velocities.

    For screw compensation see here http://wiki.linuxcnc.org/cgi-bin/emc...w_Compensation

    If your running at least 2.2.2 just use stepconf to set up your machine. It's on your menu under CNC...
