    g43 usbcnc

    Ive used a mach3 post processor someone made for solidworks to create a semi working g code for usbcnc but if i leave it as it is it holds on this line:

    G43 H1 D31 G0 X815.051 Y505.315 Z50. S1000 M3
    with this comment
    L14: D word with no g41 or g42

    now after searching i found that g43 does not like H and D and prefers I and K but then i get
    I word with no g2 or g3 or g42.1 to use it

    the thing is if i take the line out completely he takes the code, but makes a collision (seemingly in mid air)
    L69: MCA

    i have been at this for 3 days now and am on the verge of crying, since it seems i made promises that i cannot keep
    but boys dont cry! (they drink heavily instead)

    help pls...

    Try using G43 H1 by itself. You should probably have that broken into 3 separate lines

    G43 H1
    G0 X815.051 Y505.315 Z50.
    S1000 M3



    G43 normally uses H to specify the tool # for the offset
    G41/G42 normally use D for the Tool # for the offset.

    I and K are used with G2/G3

    thank you,
    it went further but sadly halted on the second tool with the following:

    G43 H2
    G0 X393.733 Y78.127 Z100.
    S1000 M3

    L69: MCA Collision

    You should use this way
    G0 X393.733 Y78.127 S1000 M3
    G43 H2 Z100.
    Using XYZ axises together in the first line will definitely result in collision
