Dear Prusa,

for the Pase Stepping:

please make the way the head is moving longer when calibrating. Resonance is most of the time not in short run, but on long runs. And maybe you can implement not only x and y calibration seperate. Resonance is bad when x and y motors are running at the same time. 

Otherwise my Core One is actually much quiter, but Resonance is not changed much.
With quiter I mean when only one Motor is running. That´s a step forward. But when both mortors are running at the same time at same spped, the Resonance is still horrible.

I am not sure whether the accelerometer can pick up the resonances at all. It will detect uneven motion of the print head, but probably cannot "hear" whether other parts of the printer get excited and vibrate along.

Does anyone else have a problem with dimmer setting? I set dimmer to "off" but it lasts only until reboot then it's dimmed again during printing. It seems that it's not remembered... ?

(btw, i do have buddy camera installed and marked as present in settings)

It's the same for me, I have to turn it off after every turn, and I also have a camera and it's marked.

I updated the printer, did the phase stepping calibration and recalibrated the input shaper, reduced some of the VFA, but the printer became much quieter.

I updated the firmware and printed some new feet for the printer using PETG Ultramarine Prusament (which really shows the VFA).

I found that the VFA was very pronounced with certain settings vs others.  Generally, there was a slight improvement.

I've ordered the accelerometer from Prusa USA (Printed Solid) and I'll see what that calibration does.

VFA's have improved for me -not a lot but a little.  Still a long way to go it would seem.  I also continue to have the corner banging - the first print after upgrade only did it a few times, but a few prints since and it's doing it a ton and even failing at times.  Never had a failure when on 6.3.3....

Running a print test now! Let’s see!!
