    It's a very restricted machine... slow rapids, slow toolchanges, not a high RPM spindle. It really is old tech.

    OK, it is the extended bed version, so it'll take a 4th axis on R/H side
    I hope you have lots of file space, as it is needed if using code from a CAM system.

    Check also that you can do a 3 axis arc move. The one I used could not.

    So, the final part program can be 60kB big.

    if it performs the 3-axis arc movement
    the check itself is not related to the part program size. MDI mode
    G91 G01 Z5 X5 Y5 F0.1 ; for instance gives you the answer instantly

    Also, you can check your OSP Data Management Card. If the "Helical cutting" is marked there?

    That is NOT an arc, that's a linear move

    Re: okuma mc4vae

    it's possible to make an arc composed from many small straight segmets. Here the memory capacity comes to play the role.

    Hi, max
    I have tried allot of cam software for my Okuma MC5 VA and came to conclusion that feature cam by autodesk works the best for me.
    I don’t know if the fusion 360 extension gives the same results as it is basically the same thing. But as I said I prefer feature cam
