    Hi everyone,

    I tried wiring my old stepper, drivers, bob and psu yesterday and setting up Mach3. I can make the steppers move correctly from Mach3, but there's a horrible sound coming from the motors, accompanied with huge vibrations and noise:

    Can anyone tell me what is wrong :( ?

    Electronics:
    - 5 axis bob v5
    - CW8020 drivers
    - nema 23 425oz
    - another chinese driver and motor (http://www.aliexpress.com/item/NEMA2...028971350.html)
    - 36V 9.7A PSU

    The last driver + motor have been bought less than a month ago and make the same weird sound, which makes me think that the BOB is the issue. It's not just one motor that doesn't work, it's all of them.

    Thanks a lot for your help !

    Cheers !

    EDIT:

    - PSU tested, all outputs are good.
