    Default G10 problem in G91

    I'm running kmotioncnc and can't get the interpreter to omit a G91.
    Example G91 G10 L2 P2 X0 Y0.1
    Would the answer be changing something in the
    Tool setup screen -> tool/setup files-> setup file?

    Hi dirtdigger257,

    What do you mean "omit"? Ignore?

    Please put more effort into your question.

    Regards

    Why would you be using a G91, nobody uses a G91 for normal programing

    I'm making some linear test cut with different feed rates and rpms
    O100
    G0 X0 Y0
    Y.1
    Z-.75
    G1 f50 x-4
    G0 z1
    G91 G10 l2 P2 Y0 (shifts the y axis 0.1)
    M99

    Because I want to incrementally change my work offset (G55)

    [QUOTE=TomKerekes;2062730]Hi dirtdigger257,

    What do you mean "omit]
    I mean it ignores it ,it should work in with G90 Or G91

    G90 works better for any type of movement you want to do, if you forget to cancel the G91 you will crash

    You are also writing the line of code incorrect, it will depend on the control you are using as to how it will work, try the G91 before the Y move

    It doesn't work better for incremental moves

    if you forget to cancel the G91 you will crash

    This was just an example I know how to keep track of my modal codes

    Try writing a 4 axis gear cutting program without using G91 The program would be way longer

    I do it every day

    Your original Post had nothing to do with using a 4th axes and cutting Gears

    A program for cutting a gear using a 4th axes, if you know what you are doing would not be any different in length using G90 for linear movements

    I think you are using the wrong G code
    G10 is used to PUT a figure into that field..... not ADD to an existing value
    - you need to do a interrogation, & a calculation before you place the value into the work offset
    ie
    #1 = #5300 + 0.1 ( note #5300 is NOT the correct variable for the value in G55 Y area)
    G10 I2 P2 Y[#1 ] EOB
    G55 EOB

    try using the global shift (00) area to adjust the origin
    also lookup G52/G92 usage, if it is what you may be needing
