    Goal; a working post processor for Fusion 360 to Mach4

    Of course there is already one in Fusion 360s Library.

    However, my Mach4 setup+machine has problems with the initial codes.
    If I copy the g-codes into mdi, from where the actual movements start, it seems to work fine.

    Another issue is that I was not able to make homing and soft limits work properly until I flipped the Z axis in Mach4,
    (Se attached immage) Attachment 485502

    With the Z flipped, it basically works like the xyz on a MultiCam Machine. (which I sometimes allso work with)
    As you may see from the immage It has to do with where my end switches are located.

    As I understad it, MultiCam has a flipped z axis, meaning that it breaks with the right hand rule, and so they kind of follow a "left hand rule"?

    So now i can see some potentional solutions:

    1: switch the X and Y axis, telling Mach4 and ESS that x is y and vise versa.

    or

    2: make all Z - become Z + in the Fusion360>Mach4 Post processor (something you might have to do when editing post processors for mulitcham machines?)

    or:

    Physically move the Home switch of the z axis to the lower end.
    (I obviously dont want to do this as you wanna have your z retracting when homing, to prevent damage)

    I figured it out.
    Fair and tidy to let you know I guess.

    I flipped the Z axis back.

    What now applies is the settings as shown in the attachements.
