Does the accelerometer help a stock Core One?
Coming from a Create 2 IDEX with a couple of BTT Mini MCU’s that the steppers ram a lot quieter. Does the accel tuning help tune the stepper drivers? The Core One is an excellent printer and my prints are coming out extremely well, I would just expect the steppers be a little quieter.

So, I'll need to run the printer for a while without running the tuning first, so the wife notices the difference? Noted. 😛

For me, using the 'new' belt tuning and then running the Phase Setting calibration and Input Shaper calibration made the printer a lot quieter.

It's worth the cost since you inevitably will be re-tensioning the belts and will benefit from a quieter printer by running the phase stepper calibration

Thanks for the info. Will add one to my next order and let you know how it works out.

I guess it begs the question though why Prusa doesn't include this with the printer or even build one into the extruder assembly?

I think the likely answer to the first is "hit a low enough price point" and the second is likely a holdover from their dogmatic "Our printers don't require such tuning because our slicer profiles are the bestest!"

Indeed. There should be an accelerometer on the "Love Board", the small PCB in the upper back of the Nextruder. It would have cost them next to nothing to include it.
I think the desire to re-use the MK4S Nextruder was probably the bigger driver than cost considerations in a full Core One. An upgraded Love Board seems a very likely feature of an improved "Core One S" at some point.

Two weeks later…. Got the accelerometer early last week and ran the tuning routine. Fairly cryptic on what it does, changed its settings for X and Y axis. Sound wise it does make a difference. The printer is quieter but also the tone is smoother. It doesn’t sound like a box of rocks any more like it used to for certain moves. Got the all important wife seal of approval last night as she said the printer was much quieter.

Is another firmware than the official one needed to use the accelerometer ?

No. The most recent Prusa firmware supports both, input shaper calibration (for clean acceleration and corners) and phase stepping calibration (for smooth micro-stepping and quieter movements at constant speed). Both use the accelerometer during the calibration.
