Vibration measurement

[azab2c]

@jamiek has a neat topic investigating Deflection measurement related investigations and findings.

Curious if something similar has been done for vibration measurement using more than one ADXL345, or similar 3 axis or 6 DOF IMU (inertial measurement unit) like MPU6050? Would be neat to do multi sensor vibration sensing for various things, with axis granularity.

I recall reading quite some time ago that Klipper overcame a limitation on i2c readout rates and that the MPU6050 has been supported by mainline Klipper for a while now.

For MPU-9250/MPU-9255/MPU-6515/MPU-6050/MPU-6500s there are also a variety of board designs and clones with different I2C pull-up resistors which will need supplementing.
