Is this too much noise? (video)

Should my steppers being making this much noise when sitting idle (powered up and linuxCNC on/in control)?

Any noise is bad. Thank you for confirming.
Anyone have recommendations on how to diagnose causes?

Hi,
a stepper driver uses pulse width modulation to regulate the current it supplies to a stepper.
Have you wondered why it is that you use a 36V (or 48V or......whatever) supply to your driver but is says clearly on the stepper 4.2V?
Lets make it simple and assume you have a 42V supply. If the driver switches the 42 V to your stepper for 1usec and then off for 9 usec then back on for
1usec and so on effectively your stepper sees 1/ (1+9) x42=4.2V. So even at idle your driver is switching on and of rapidly. Ideally it would switch fast
enough that you couldn't tell but if it switches more slowly, say 15,000 times a second then you might detect that as a buzzing sound.
I am guessing that the sound you are hearing is of that type, and while annoying should cause no problems. The real question is 'do the motors do the
business when commanded to move?'. Who cares what they do when stopped....its what they do when moving that's more important.
