@lui2004 did you try changing
M203 X30000.00 Y30000.00 Z500.00 E6000.00
to
M203 X6000.00 Y6000.00 Z500.00 E6000.00
and then turn off/on printer to be sure the change is active?

I don't see errors in M122 and config.

[lui2004]

yes i have changed the values but still the same with noise

[JoergS5]

@lui2004 I watched the video with audio on now
My impression is, the most noise don't come from the steppers, but the fans. It's difficult to decide. Probably after homing some fans are activated because something heats up (heatbreak fan eg).

Your trapezoid spindle for Z movement is black, this may be abrasive from some spindle nut or you needed lubrication. There may be too much friction between nut and spindle. This could produce noise also (and has the danger of slip-stick and inexact Z movement also). The coupler between stepper and spindle is of a type where the stepper and trapezoid axis must match exactly. Better would be dog clutch (Rotex coupler, Oldham). They are better than those aluminium coupler with horizontal gaps.

It's hard to tell from the video if it's fan noise or the motor idle noise. The creality motors are a bit noisier on the Duet I think. There is a bit more whine from them.

M906 X580.00 Y650.00 Z580.00 E650.00 I10 ; Set motor currents (mA) and motor idle factor in per cent

Current setting on the Duet 2 WiF/Ethernet is done in steps of 100mA and is rounded down. Current setting on the Duet Maestro is in steps of 50mA and rounded down.

So keep that in mind when setting your currents.

this parameters are from marlin

M906 X580.00 Y650.00 Z580.00 E650.00 I10 ; Set motor currents (mA) and motor idle factor in per cent

so if i have the Duet wifi how to set up ? like this ?

M906 X480.00 Y550.00 Z480.00 E550.00 I10 ; Set motor currents (mA) 

[JoergS5]

@lui2004 can you locate what is loud? X, Y, Z steppers or fans (and which fan)?

[Phaedrux]

Those values will be rounded down to the nearest 100ma.

So this: M906 X480.00 Y550.00 Z480.00 E550.00

Will actually be this: M906 X400.00 Y500.00 Z400.00 E500.00

@JoergS5

all motors

i will try this on monday: https://duet3d.dozuki.com/Wiki/Reducing_Stand-Still_Noise

Hi

the noise from the motors seems like rustle
