Measure Fan Vibration

Would it be possible to add Fan Vibration Testing and display results in an Image format?

Skirt Fans are not particularly quiet, they often vibrate and apart from the annoying noise, they must affect other measurements.

It would be nice to have a tool to display graphically the impact of vibrating fans and results of adding various damping materials...

Hi, I'm not sure how to measure this in Shake&Tune as it would require a microphone or something like that and I can't compare it to a baseline. Also, skirt fans shouldn't have any effect on the prints...

As for the fans that do have an impact on prints (i.e. toolhead fans) and can produce VFAs, they are already recorded during the tests as you can see in the docs here: https://github.com/Frix-x/klippain-shaketune/blob/main/docs/macros/axis_tuning.md#fan-behavior

However, if you have a specific idea in mind, I'm open to it :)

A good quality fan would probably have little or no affect on the accelerometer measurements, however my skirt fans running at full speed generate considerable noise/vibration, so much that I had to add damping between the printed part (holding them), and the frame.

It should be noted that the printed part holding the fans is only anchored with on fastener, vibration is almost guaranteed but is it measurable by the accelerometer?

Instead of moving/vibrating the gantry and measuring the accelerometer, would it be possible to ramp the fan up and down to produce a graph. This would tell us at what speed the fans could caused issues, or indeed if the fans required changing... perhaps looking at the fan_maybeproblematic.png would be enough...

I guess we can close this...
