  1. Re: Why does this program make the machine crash? - with video

    What happens if the G18 was replaced with G17 ?

    ... I suspect you may get the same rapid move when the program rewinds, hitting the M2/M30 forces some sort of cancelling of H1 or other machine...

    That gonome can be turned off/on ... same as the crosshairs
    Try F9 (crosshairs)

    Re: G43 Cutter comp and G03 arc problem!

    It is strange behaviour...
    Normally G43 is tool length offset only, but, there seems something is occurring in the background ie cutter comp is/has been activated

    So try this... add G40 to the...

    Re: Crazy acting milling machine!

    Check if Feed/Rev has not been activated.

    A feed move that is programmed for feed per minute WILL move very fast if you forget to switch back
  7. Re: Fanuc 16 changing X axis sign in G53 from minus to plus

    G53 is the machine co-ord system

    Any values placed in this line are relative to this home position. There is NO relationship to the work co-ord...

    Re: G43 Cutter comp and G03 arc problem!

    What machine & control ?
    Does #1 offset have BOTH the H & D fields ? (I'll assume no)
    G40 cancels cutter comp
    G41 is to step LEFT of the profile (climb milling)
    G42 is to step RIGHT of the...

    I'm concerned about the slower feedrate of F18.8

    Re: C axis unwinding on Haas 5X

    It would be either a post or programmer error... I'd lean toward a programming error.
