    yes Hilton, Alcohol is good.

    Its amazing, how alcohol can have different affect on things, On machinery, its stops them from humming, yet in humans, it get us to start humming, And if you get enough alcohol in certain ones of them, you can get harmonic humming. hmmmmm hmmmmmmmm hmmmmmmmmmm

    That's interesting. I get cleaned out with alcohol occasionally and I've never stopped. Think I'll try it again tonight.

    Thanks ~ Cleaned out with alchahol in the air lines and it stopped.

    I had a similar but different issue, with the x-axis. Had service in. Had a blocked air-bearing. Can you see anything on any of the surfaces that the bearings ride on? I had a white film on mine.

    AND, for all the smart aleks......

    Are you sure it's not a Dynamo Hum? (Rimshot goes here!)

    HUM

    IF IT'S NOT AIR RELATED A SERVO MOTOR GOING BAD
    WILL MAKE THE EXACT NOISE AND SYMPTOMS YOU
    ARE DESCRIBING. SOMETIMES IT'S AN ADJUSTMENT ON THE SERVO
    BOARD TO CORRECT THE HUM FROM THE MOTOR. I'VE HAD THIS
    SEVERAL TIMES ON THE OLDER WORLD CONTROLLERS. I DON'T KNOW
    IF YOUR "NEW " CONTROLLER OR SERVOS WOULD HAVE THE SAME ISSUES.

    I have had the same thing.. on an Fx
    I went to clean the z rail and took some of the screws loose on the case...
    Seen I couldn't get it off without removeing the head. So just being off a tad it would rub at times when I had the temp up in the room or just whenever it felt like it.. I found the spot it did it the most in and reajusted the case.. Problem went away... Glad it wasn't anything else wrong.. like some of the replys above
