Wiggle or no wiggle
Question for the experts. Which is better for the Core One. Hold it stable like bracing it against the wall and holding it still or mount it on legs with squash balls and let it wiggle.
RE: Wiggle or no wiggle
The moving mass is near the top of the Core One, that is the reason it tends to woble a little more.
My Core One is on squash ball feet, but a very rigid table. Works OK for me. Machine tools are rigid. but I haven't seen it necessary yet to make the Core One completely rigid. Keeping it rigid may help with tall thin prints, to keep any shake out of the print bed.
RE: Wiggle or no wiggle
I went the wiggle path. I can see a scenario where printer movement could cause random additional g forces on the printhead simply by printer movement not being in sync with the printhead movements, a non moving printer would remove that disturbance. I don’t know how to make the printer not move, sitting on very heavy tool bench (hundreds of kg of tools) bolted to the wall the printer still managed to shake the bench and transfer vibrations to the building. I switched strategy to put it on a dampening stack made from flor tiles and sound solution material and it now sits on a much lighter desk on wall consoles, the desk does not vibrate. I don’t see anything negative on prints if anything I have less problems with layer shifts but then that can just be a run in thing.

RE: Wiggle or no wiggle
mine is on a rather stable table and, just using the standard rubber feet, it doesn't more/shake/wiggle. Printer seem to be happy, it works as expected. VFAs still present though.

I didn't notice VFA's until I was told they were there and now I see them everywhere 🤨 . I suppose what I mean by that is VFA's have always been there, I just thought it was "normal". I had them on my MK4S as well but not as bad as the C1.
As in a different thread, I have a very sturdy table but even it was shaking enough to be annoying. Replacing the crappy Prusa feet with a TPU based foot mod helped. I printed the Hula feet (mostly for fun) and they cut down a lot on table vibration but the VFA's are the same as before so no improvement there. Anyway, I personally don't care at all about cosmetics so it doesn't bother me... yet...
RE: Wiggle or no wiggle
Let it wiggle - you should see how much the H2D moves around! It's on very squishy feet so its designed to let the printer shake around a little - much more then my Core One, and its absolutely fine.
RE: Wiggle or no wiggle
In my case the wiggling was making the old table creack in a really worrying manner, thus the table update. Superstable, and my wife doesn't complain about the noise anymore 😃
RE: Wiggle or no wiggle
Mine just sits on my garage work bench. Prints look great. It's fun to watch the printer dance.
But if it really bothers you, perhaps weld an I-Beam onto the top edge and bolt that to a rigid
concrete wall? 🙂 Just kidding. I understand the concern. But it seems just fine on a
rather solid table or workbench. I would not use a folding table, for example.

RE: Wiggle or no wiggle
wonderful picture 😀 just for a moment I though "...what the heck..." 😀
From a purely scientific point of view, I would be interested in a side-by-side comparision between two core one, one swinging and one not, to see if differences arise (eg the belt go out of tune faster, etc). Give the apparent fact that no core one seem to be equal to another, even the factory assempled ones, in term of performance, noise, etc etc such a comparision probably can only be done at Prusa.
oh well...
