Loud isn't very specific; but common issues would be high inductance and low voltage or one phase not connected properly.

Elaborate a little on the sound, motor specs and supply voltage please.

Rules out one phase. 12v presumably? Its probably as quiet as it will be without enabling stealth chop or what its called.

In particular the D and V parameters. Not familiar with the Ethernet version so others will have to provide any further guidance.

have you read

@Veti Been testing all day and still sound like poop. Thanks though!

smith505

@bearer Also was messing with D and V parameters. Helped slightly but they're still really loud.

are you sure about those currents?

I don't know if what I've done is correct but I've solve the noise of steppers changing step-per-mm

i dont know about you, but i prefer correct prints to noise.

zecchi

@Veti

I'm completely agree. Nevertheless the change is of half steps ( or minus)

I don't understand. How does that solve the problem of noise? If the steps per mm are wrong the print will be the wrong size. Do you solve that by scaling the model in the slicer?

smith505

@Veti Yessir im sure about the currents as the ones in the link you put are the same besides the Extruder.

Phaedrux

@smith505 You may be able to reduce currents a bit and still have good results. Try 700, 600, 500 and do a test print between. There should be some improvement in sound. How low you can go on current will depend on your acceleration and speed settings.
