Motor idle noise ?



  • 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.

    On Z.

  • I've heard a noise not unlike this as well. When I was jogging the the x/y carriage and z axis around for bed leveling, ever so often I would hear it whining at me. I could jog the y or x or z and it might go away. When printing I really couldn't hear it. Following this post because I'm curious. FFCP/DuetWiFi.

  • Try changing the idle %. M906 X1600 Y1600 Z900 E1000 >I30< to a higher or lower setting.



  • I have the exact same issue with high frequency sound from the motors.. Gets really tired from listening to it. My old board with TMC2100 was totally silent.

    I think DC42 wrote in another tread that he wanted to know if more people had this issue and that the TMC2660 had tons of possible tweak options…


  • administrators

    I'll try a few different settings on my Kossel and provide some suggestions later.



  • 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.

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

    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.



  • @dc42:

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

    9.3mH, 750mA, and 5.75 Ohms/phase, 1.8 degree/step on the X and Y motors. Just standard FlashForge steppers.

    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?


  • administrators

    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

    I did this and the pitch increases but it's just as loud.

    This is what it sounds like by default, 1.18.1

  • I've got a similar problem... Used this stepper motors: 17HS19-2004S1

    https://www.omc-stepperonline.com/de/hybridschrittmotor/nema-17-bipolar-59ncm-84ozin-2a-42x48mm-4-drähte-w-1m-kabel-and-verbinder-17hs19-2004s1.html

    1.8 deg 2A. Actual running at 800ma. Already tried 300 to 1700 with no effort....
    Running the DuetWifi on 24V

    If I switch on the printer there is no sound, but as soon as I home the axis, there is an awful beeping / wheening on all motors in idle. Also if they are moving, they are quiet loud. On my Anet A8 with TMC2208 (under 12 V) there is nothing to hear?

    Are there any solutions on this problem?


  • administrators

    This is still on my list to look at. AFAIK Trinamic doesn't give any guidance for setting the chopper control register values, so I need to experiment.



  • Today got my new pancake Extruder Stepper motor. Same issue, but less noisy. ( https://www.omc-stepperonline.com/de/hybridschrittmotor/nema-17-bipolar-18deg-13ncm-184ozin-1a-35v-42x42x20mm-4-drähte-17hs08-1004s.html?search=17HS08-1004S )
    Is there any schedule from which the problem is addressed? Unfortunately, I do not know what else I can do about it ..



  • oops, I just changed my power supply from 12 to 24V, and now I have noisy idle motors too. What's funny is that the volume changes with the position, I suspect it's the microstep position I'm hearing.
    I have an anycubic i3, here is a picture of the motors: 0_1529094485902_IMG_2032.jpg

    here is my configuration:

    The irony that I wanted to go to 24V to reduce the noise is not lost to me...



  • Can I fiddle with the M350 command live in the web interface when the motors are running (at idle)?

    I am trying to change the M350 S parameter and I don't hear a difference.



  • @dc42, what registers are set when using I999? And what params affect the motor noise?
