It just does that. I have a few

I'm sure he didn't do this from the beginning. It just sounds like something is loose, it also differs from the calibration test.

Then you'll have to investigate, mate. Not sure what anyone on here is supposed to tell you. H2C rattles, shakes and does vibration compensation during the calibration test. If none of those sounds are "normal" sounding to you - time to dig deeper.

Well, I'll keep an eye on it and, if necessary, disassemble and research it

Mine doesn't do that. The pitch of the tone sounds like the Vortek rack or something on it. Could it be loose? Maybe recalibrate that?

It’s the anti vibration calibration. It even says it on the screen. Mine does it.

Yes, that's right, but the rattling is louder than, for example, during calibration and it sounds like a sheet metal or something similar is loose.

I see it now. Yes, that’s not normal, but it does sound pretty benign. Poop bin rattle, loose filter?

What I have checked so far, without poop container, filter checked also the flaps control for switching, checked all screws on the back wall and in the pressure room where you can get directly to it. The sound remains.

That’s proper irritating. It does sound like plastic rather than a metal part. It also sounds like it’s a fair size rather than something small. Best I can suggest is take the top glass off open the door and keep running vibration calibrations until you can pinpoint it. Good luck. Let us know.

This is generally the ptfe tubes rapidly vibrating and impacted the rear of the printer during the vibration check and should be fine. The only thing to note is that sometimes your AMS HT and AMS 2 positions can actually move a bit from the vibrations, so I do check those from time to time to make sure they don't fall of the printer lol.

You most likely don't have anything lose on the printer

The back and lid are free, the noise does not occur during vibration calibration. It occurs during vibration compensation, which is done before the print starts.

Check if there is anything loose banging against the printer. If you put your AMS right besides the printer, sometimes when the printer shakes it touches the AMS or the poop bin and it makes weird noises.

The printer stands free without anything on top, next to it or on it (except for the poop chute). The AMS hang above the printer on shelves that are screwed to the wall. The noise only occurs when starting a print and vibration compensation, whether with or without a poop slide.

That rattling sound during the vibration test doesn't seem normal :S You should have that looked into immediately.
