  1. Re: All VMCs.... lead screw's thrust bearing preload

    I ditched the 7304 bearings and shim and replaced them with proper ballscrew support bearings of the same dimensions. They come preloaded so just grease and install. Couldn't get less than 0.01mm...

  3. Re: I screwed up in DI and now my machine won't power up.

    Hope it is something like a battery or power supply and not a cpu board
  4. Re: I screwed up in DI and now my machine won't power up.

    I am just as stupid.
    Have used the start cnc probably 10 times on one 4020 and once on a vmc10.
    Like you I expected it would restart the software.

    Both machines worked fine afterwards.

    Re: Rs232 problems 88hs

    I heard from ITS that they are interchangeable. I swapped the cards and rs232 works so the fault lies with my 1030-1c card.
    I will send off for repair.
    Cheers

    Re: Rs232 problems 88hs

    Also maybe worth noting the other 1030-1b card in our other machine is without video. I believe these were available both with and without video.
    The 1030-1c card we are having issues with is also...

    Re: Fadal VMC2216 with Calibration issues

    Ball screw pitch compensation would only be microns not the error your talking . Unless someone has seriously stuffed with it.
    Check the parameters for ball screw info.
    Maybe the setting has been...

    Re: Fadal 4020 Moving-measurements needed

    Centre to centre 104cm
    Casting is 68cm approx so you would need that measurement between the forks

    Not a kit just worked it out myself.
    22 years in the bearing game helped as suppliers of this bearing set a pretty hard to find.

    Correct. The alarm 'not ready' is same as having estop pressed.
    I assume the not ready is due to the spindle drive not powering up.
    Will look to check these items and advise the outcome

    Re: Feed hold stops spindle

    I have a 8s and a 10hc. The 8s spindle stops the 10hc doesn't. I quite like that it stops. Great to clear a bird's nest or change an insert mid rough cut. Check clearance to the jaws in dry run.

    Remote not I am interested in. Not sure where it plugs in to. Mine was never optioned with one.

    Food for thought. I would like to try it but I also don't want to stuff it up.
