When the machine runs in circle, there will be some vibration noise as you have seen. According to our test, the noise will be noticeable when the speed of Y-axis is from 200-800 mm/min. The entire working platform amplifies noise like a speaker, which is not avoidable since our machine is made of metal.
But, no matter what the speed of the Y-axes is, the component speed in the Y direction will appear in the above range.
Sorry for the inconvenience, and we are working on the silent module now.
Here is a video for your reference.
