@dc42:

Send M906 I100 to set the idle current to 100% so that you can hear the noise better. Move the motors a little to turn them on. Then send the command I suggested and listen for any change in the idle motor noise. Ignore the error messages.

hmm okay. X is maby little little less noise. hard to compaire. But Y have same sound. so not much diffrence there.
There is more noise on Y axis. it has always been so. But it is same motor on Z. and they dident sounded like this with my mks board and TMC2100.

They work nice and go very nice when they print. So just the idle noise.

i use version 18rc1

@dc42:

Try sending this command:

M350 I999 X33203 Y33203 Z33203

(that's a letter I before the 999). This is a bit of a guess because I don't have any motors with specifications close to yours to test with.

Caution: don't play around with the XYZ values without understanding the TMC2660 data sheet. To go back to default values, use M350 I999 X65972 Y65972 Z65972.

There is a slight bug in that sending this command will enable the XYZ motors if they are not already enabled, also disabling/enabling the motors will change the values a little. This will be fixed in the 1.18 release.

When i send M350 I999 X33203 Y33203
that come up.

21:16:34 M350 I999 X33203 Y33203
Drive X does not support 33203x microstepping with interpolation
Drive Y does not support 33203x microstepping with interpolation

do i send it or change my config?

what does it do and does it only apply on my motors or other with same problem can try it?
how did you come up with that numbers?

@dc42:

What is the inductance of the noisy motors, and what current do you run them at?

2A runing at 1600mah
3.0 mH+-20% (1KHz)

My titan i cant Look up now. It is there "official motor" 0.9.

Great! Thanks. Will try it later

That wiring is correct.
My bltouch is working perfect and i tried a extreme bed compensation with 1.5 mm high on one side and 1.5 mm low on other side and i got a Perfect first layer

BUT is there a code or something so you can "fade" out the compensation. that compensation makes the Z move around and can make ugly prints.

I had that on marlin with my mks board. 3mm was the compensation Then it dont compensate anymore and the print is level.
I have not tried that gcode that fades out in Marlin on my Duet. And i am not on my computer now so i cant see what that gcode is.

I have playing around with diffrent idle currents and microsteppings and it dont change a thing. Same sound.

BUT my Z motor is quite. No sound on that.
I "heard" that when i playing around and start them one at a time. If i only start Z there is No sound.

So all my 0.9 deg motors are making that sound. X, Y and extruder. Have titan with ther 0.9deg motor

i run everything on 24v.

i have this motor idle noise when my motors are on. i dident have that when i have the mks board with TMC2100.

is it normal or what can it be?

This on X and Y.
0.9 deg and 2A. Running in 1600mah

On Z.
