TMC2208 SilentStepStick not Silent ;(
low noise only at 30mm/s, but on speeds more than 60mm/s - noise like on this video
Sound volume increased for this video, so, some other sounds also hearable. But others sounds does't matter. The main problem in motors noise.
Any help?
#update
I'm using mega2560 + ramps1.4
Firmware: repetier

What are your steps/mm? One possible explanation is that you are using 8-bit electronics and firmware that has to use double stepping to achieve 60mm/sec speed. Double stepping will mess up the microstep interpolation logic in the TMC drivers. AFAIR, Marlin switches to double stepping at steps rates around 10kHz, which would correspond to a speed of 50mm/sec if you have 200 steps/mm.

If you have to stick with Mega2560 and Ramps, you can try to use a separate 24V or 36V powersupply for the stepper drivers only. That made a huge difference for my TMC2100, but it really got silent with 32bit controller ( RADDS and RRFirmware)
Thank you for advice with separate power supply, I will to try.
But I can't understand difference with mega2560 and 32-bit controller with the same stepper driver and only 80steps per mm.

The 8bit MPU is able to produce the step-pulses fast enough, but they are not evenly spread. That's why they are noisier.
This is mistake hypothesis.

Hello all,
Mr. Stephan replied to my question about TMC2208 noise:
It turns out that the description of the goods is false, since it is written that they work at "Motor Voltage - 5.5 - 36V" and silent.
But they are silent only at >= 24V
Mr. Stephan replied to my question about TMC2208 noise:

The 12V power supply can also be a problem, because stepper motors are controlled with a constant current.
So at higher speeds the current can not be reached with a 12V power supply, please try a 24V one.

On high frequencies the Skin effect is working, so the resistance of the motor coils are high and you need more voltage to reach this current.

Hi. I have recently incorporated TCM2208 drivers to my machine. And I have found this:
12V is not enough. Steppers were weak, loosing steps and in standstill, they screamed in StealthChop2 mode.
Then I used Dell charger 19.5V/4A just for steppers. Torque is much higher now. When printing and moving fast (120mm/s and 200mm/s), steppers were loud. But when I lowered current (from 0.9A to about 0.5A), steppers became quiet and torque is enough. Now I am happy
I am going to try SpreadCycle soon, but with enough torque, I will probably not use it.

It would be helpful to know what motors were used by @abuharsky and @kolin. They may have been low current high inductance motors, which are not suitable for operation with a 12V supply anyway. Hint: if a bipolar motor has "Rated voltage: 12V" in the specification, then it is NOT suitable for use in a 3D printer with 12V power, because much more than 12V will be needed to reach sensible speeds.
