RE:
The default values are for X: EI 60Hz and for Y: EI 50Hz.
After the calibration, the printer now uses for X: ZVD 54Hz and for Y: ZVD 59 Hz.
My calibration results turn out differently: Also using ZVD on both axes, but 46 Hz resonance in X and 41 in Y. Listening to the tuning process, the resonance frequencies seem plausible -- the sound becomes a bit harsh around those frequencies, i.e. with notable harmonics. Still, the frequencies are quite a bit lower than yours, and than the default values. I did double-check the belt tuning, and it's 83 and 84 Hz, respectively.
Looking at your tuning results, I am surprised that the Y axis is stated to have a higher resonance frequency than X. There's definitely more moving mass here, so shouldn't that be the slower axis?
I am currently running the VFA test print again. Turns out that the only glossy PLA I have (besides the Galaxy Black I ordered with the printer) is white -- probably less than ideal, but I am using that at the moment. Also got the two small samples which came with the printer kit (Jet Black and "Viva La Bronze" PLA). Tjose are only 25g each, but that may be just enough for the test print, or at least for the more interesting (s)lower half. I'll try one of those next if the white comes out inconclusive.
RE: Prusa CORE One kit assembly instructions
Would it make sense to post your VFA / Frequency / Input Shaper issues in the respective thread for better overview? 🙂
I think we should return to the actual topic of assembly instructions and possible tweaks/twists and strange things happening there.
Thank you and have a wonderful weekend 🙂

I was just wondering the same, after realizing that we are not in the VFA thread here... Agree that we might want to move back over there. But on the other hand, I would argue that "How to assemble a Core One to achieve VFA-free printing?" is the big unsolved mystery regarding the assembly instructions. 😉
RE: Prusa CORE One kit assembly instructions
Ok, I'll report back later when the part is printed =)
Thanks, post your results here when it's done to keep this topic related to build instructions 🙂

Perhaps posting our findings from the VFA thread here would be best. Ultimately, I hope there’s a stickied post with a concise list of things to do with a new Core One to get the most out of it.
RE: Prusa CORE One kit assembly instructions
Anyone who has completed the kit:
Did you have the correct magnets for the Side sensor base?
It says that '5x10x2mm magnet (2x) found in the Electronics & Fasteners package' are required, I can find them. I have 10x6x2 , but a Prusa employee has stated theyre required for another part of the assembly later on.

I used the 10*6*2 magnets in that step, and did not miss them later. 😉
The magnet in the moving lever will stick out a bit on both sides. Make sure it does not stick out too far on the top (open) side, otherwise the lid of the sensor housing will block its motion once installed.

Cheers Jurgen, thats what I was going to try but the comment from Vojta stopped me in my tracks. There's a definite oversight that needs clearing up.

I just added another comment in response to Vojta's, pointing out the apparent error.
But I have not received much feedback at all from the Prusa team regarding my various comments in the instructions. In one case they incorrectly claimed "this adjustment is done later in the build"; in all other cases, silence. Disappointing -- if I deal with various oversights as one of the early adopters, and take the time to write comments and suggestions, they might as well implement or at least acknowledge them.
They seem to have responded better to others' comments which just point out a typo or such. Probably Vojta is more of a technical writer who can directly address formalities, but has to go back to the technical team to review suggestions on the build and alignment process. And the latter does not seem to be happening (yet).

What was the bold part regarding ?
I saw your comment about 'point of no return' on the filament sensor/square nut issue....I read that just as I passed the point of no return 😂
RE: Prusa CORE One kit assembly instructions
The one response which claimed a later adjustment (which I did not see anywhere in the following sections) was about squaring the X rail with the Y rods. Ah, never mind -- it will all gradually be sorted, I'm sure.
RE:
After watching a build and the struggle with limited space to address issues I've decided the acrylic panels and door will be installed after testing and a quick PLA print. I'll override the door sensor as needed but think this will make it easier to correct any issues during that time.
RE: Prusa CORE One kit assembly instructions
How are you guys getting the xy belt tension dialled in? The prusa app way is pretty hopeless as most of the time it's completely unresponsive to my twanging.
Regardless, I'm seriously impressed with the printer so far.

How much does the frame depend on the panels for rigidity? Monocoque design relies on the skin for much of its strength, but I’m not sure if this qualifies as monocoque. Maybe someone else who has finished their building can comment on this.

Im no structural engineer but I don't think they provide much rigidity at all. They're only acrylic and held in by plastic rivets, just a cosmetic and thermal thing I guess. They look amazing, even now mine have dog hair and fingerprints all over them, they're also a static magnet unfortunately.

Web version https://belt.connect.prusa3d.com works better. Don't forget to turn off motors (it's missing in instructions there).

I shall give that a try, thanks.
RE: Prusa CORE One kit assembly instructions
I wish they'd offer the mechanical version like they did with the MK4. Audio based tuning with the technical differences in CP mics can cause issues. I needed the tool to get the Y axis right on my MK4.

RE: Prusa CORE One kit assembly instructions
Yeah I remember some mechanical thing I printed for my Mini+.
I think I'm somewhere near now with the audio one from the webpage linked, the webpage based one at least seems better than the Prusa app.
RE: Prusa CORE One kit assembly instructions
I'm sure I read in the instructional guide to do it with the printer switched off......
Either way, I also used the web version for my MK4s with results that I never had any issues with. Hoping the same is true here!
