After using my Core One+ for 6 months I connected the accelerometer and did a calibration (considered unnecessary when factory built but I have made a couple of changes)
Initial reading
* MZV 60Hz
* MZV 48Hz
Calibration result
* MZV 47Hz
* ZVD 53Hz
It seems fairly different but I don't know if it is. I didn't have VFA complaints so I didn't bother with a before and after print I’ll just monitor for any issues.
Note Prusa has released firmware with a major change to input shaping this week.
