Stepper motors noise when enabled without moving.
My z front left is making a weird noise once enabled. It's the only one that makes this noise. Other motors are quiete when not moving... is it normal ?

Some noise while holding is normal if not in stealthchop mode
thank you. i was worried
....some say don't..but I set each steppers stealthchop to 1. It cuts down on that tiny high pitch whine you can here while idle ymmv
Stealthchop is not enabled on mine
that's fine... adding stealthchop=1 will quiet them at idle
i'll try that
setting it to 1, as soon as they move at all, your right back in normal (and desired) spreadcycle mode.
but in the klipper documentation they say it can lead to issues changing that ... if it s not an issue i can live with the noise
it's 'an issue' WHILE MOVING as it can skip microsteps. But not an issue NOT moving. As soon as you move you are right back in spreadscycle. Klipper or no Klipper, this is universal across almost every stepper driver system. My massive CNC router table running 6A 48V 942 oz/in NEMA 42 steppers are configured this way. Without it you can SEE the stepper motor hum in the metal frame work at an idle.
so i just specify stealthchop_threshold: 1
seems like it is already in the default config lol
i changed to performance settings and set the stealthchop_threshold: 1 and it's nicely quiet on idle
thanks
