    Convert Radius/Arc's R or L to coordinates I,K

    Hello!

    I'm using SolidCam to generate code for my machines (lathe) and i use default post processor in SolidCam "Okumall" and it work perfectly for most stuff. But there is problem with radius, arc's etc, post processor gererate it as "L", is there any way to set up this to get that "L" in "I and K" coordinates.

    Thank you

    i tried to edit this:

    else ; CW
    gcode = 2
    endif
    {['G'gcode]}
    {[' X'xpos]}
    {[' Z'zstart]}
    if arc_size eq 360 then
    ycenter = -ycenter
    {' I'xcenter_rel, ' J'ycenter_rel}
    else
    if arc_size >= 180 then
    radius = -radius
    endif
    {' L'radius}
    endif"

    to this:


    ;-- arc plane --
    if arc_direction eq CCW then
    gcode = 3
    else ; CW
    gcode = 2
    endif
    {['G'gcode]}
    {[' X'xpos]}
    {[' Z'zstart]}
    if arc_size >= 0.1 then
    ycenter = -ycenter
    {' K'xcenter_rel, ' I'ycenter_rel}

    endif"

    it was close but machine not accept...

    does anyone know solution?
