Question The value of adxl345 z is always over 9000

[tianyi7250]

I installed adxl345 on voron 0,
But it turns out that the Z-axis is always more than 9000 values
What is the reason for this?

How is your ADXL oriented? You can check on PCB directly, it has the symbol with 3 2 arrows showing coordinates. It may very well be vibrations on other axes.

Is there anything which would cause additional vibrations like fans running?

This is normal - you are seeing gravitational acceleration.

1. Thank you for your response.
The ACCELEROMETER_QUERY has returned a z-axis value exceeding 9000,
and I have utilized "MEASURE_AXES_NOISE" to obtain values ranging from 1 to 100.
Would this be appropriate? Additionally,
may I proceed with measuring resonances?
thankyou

Looking at those numbers I'd guess your printer is sitting upright and is on Earth. Try an experiment: Lay the printer on its side and I bet the X-axis will read about 9000 and the oothers, closer to zero. Then take the printer to the moon and see if the 9000 values change to about 1500.

Earth's gravity is about 9.8 meters per second squared in the Z direction.

Alternatively we can try going to the orbit with it and see how it changes in microgravity
