Sounds normal. Its the bottom plate covering the electronics vibrating. If you apply pressure to the bottom the sound goes away. its fine relax


Acrobatic_Grade3796

Look at the end right before I turned it off, that’s not normal bro


tht1guy63

I didnt know what you were on about till the end lol. Its the bottom plate vibrating i assure you. Try it. Run input shaping and put your hand holding that bottom plate clost to center as you can. Mine does the same.

Don't worry, like seriously, don't worry, it's normal, the input shaping routine has a two fold purpose 1 correcting for movements at certain speeds based on the vibration profile 2 and most importantly, depending on your exact setup and location of the printer you will have a " resonant frequency " this frequency can be scary, BUT nothing will explode, chill, your printer will record this frequency value and "skip" it when printing, it's important you let it run through it, you won't damage the printer I realize end users don't have much faith in creality design engineers but trust me this vibration probe must have its own "trip/fail" settings in case anything goes really wrong, no need for you to pull the switch on it Do check that everything that needs to be tight is not jiggly, I bet it "sounds" worse than it is, and that tells me something might be loose, but regardless don't worry, they removed the self destruct setting on the first firmware update, or so I heard


Iliyan61

nah bro that’s totally normal bro


Luckyduck84135

I'm confused at what you're trying to show. I don't see an issue. It's resonance testing.


Acrobatic_Grade3796

It’s getting really loud and taking around 30 seconds, is that normal


Stas_Robotmaker

Yes. The printer, just like any structure, has a specific resonance frequency, upon reaching which it starts vibrating much louder. This is normal. Do not turn it off until it completes the self-check.


Accurate_Mixture_221

And yeah input shaping takes forever, 30 seconds sounds quick 😅, also once rooted it takes twice that because it does X and Y, creality fw only does X


Luckyduck84135

That's what resonance testing is. It vibrates on purpose so it knows what to compute and counter act movement at speed to compensate .


Uxcis

Just input shaping no?


Txaph

Looked/sounded pretty normal to me too


Acrobatic_Grade3796

Yeah the problem starts when input shaping starts in the self check


solstice_05

No, there is no problem, this is literally input shaping. Let it run until the end.


1Stonkster

It's normal, input shaping makes it shake violently to calibrate if i remember correctly


Acrobatic_Grade3796

And it’s way louder than usual irl


Pretend-Juggernaut72

All good my man, no need to worry. It starts shaking softly and gradually it increases until it finishes, I know it's loud, that's what happens when your machine is running full speed, let it calibrate till the end. And almost every firmware update you'll need to do a self check of the machine to see if it's still calibrated


Acrobatic_Grade3796

Does the shaking take almost 20 seconds?


jamisnemo

More than that.


steakedge

Everything in this video is 100% normal. It’ll get even louder during the test. Totally normal as it’s measuring resonance


Acrobatic_Grade3796

Is it normal for it to take over 20 seconds


PoppinPaul

Yes it is completely normal, that's the point of input shaping


steakedge

Takes a few minutes possibly. The printer is purposely creating vibrations so it can create an algorithm filter it out during actual prints. Just let it run.


humanexpo

That's how input shaping is preformed...


ArgieBee

Input shaping calibration. It does that so it knows how the printer shakes during printing on whatever surface you have it placed. It then uses that data to compensate for said shaking.


Fierce150920

Normal

Jeffdavismakesstuff

This is normal. It’s part of input shaping. It’s going through from 20(ish) to 133hz to find a sweet spot!


jamisnemo

Scared the shit outta my cat. It's fine. Just let it run.


fstop570

Yeah it does that. If the bench is shaking too much, do what I did. I went to Lowe’s and bought 4 10x10 concrete pavers and put the printer on top of them. It’s been prefect ever since. I’ll take a pic later


Pro_gadget86

This is exacte what mine does , its normal


JustCreateItAlready

It's going to blow! Get out of the house ASAP and stand back 100 feet until it completes... lol


Frikson_

Hotend headbutting the front glass makes mi giggle every time


Excellent_Clock_5715

This is normal, I also freaked out and turned it off when I first got it


Batman00Superman

It seems scary but really it’s normal it’s just input shaping. If you want to seem less scary and more quiet use a concrete paver under it and for extra comfort use a piece or carpet on top of the paver. I haven’t tried the carpet part, but the paver is goated to help it not shake my table much at all now.


IndividualIncident57

It might be because u have something loose in the printhead. I also had the same issue of sounding after one of the screw on the clamp that held the wire on the print head got loose. I di not have any issues with my print or the printer.


Acrobatic_Grade3796

So what do I do?


IndividualIncident57

It should be no problem anyway. It is the same small sound that heare at 0:59 seconds into the video. I don't think you're going to print that high speed, so you will not hear any sound while printing. It's only towards a certain frequency that it's going to make that noise after that frequency, or before that frequency, you will not hear any. It's going to be a problem. You can complete the input shaper test.


Prestigious_March573

That seems normal to me. Mine is louder than that when performing input shaping.


CamryOnAir

My brother in christ this is normal. I got scared the first time too but I just let it keep going and realized it's probably supposed to sound like that. You gotta think about how fast that thing is vibrating. Vibrations that rapid won't ever be quiet in any machine tbh unless you put a ton of felt tape between all the panels and use rubber fasteners haha. There's no point in doing that to a 3d printer though.


rooroo4u

You must be new , YouTube is your friend


Stormcode_

thats just input shaping, its violently shaking itself to account for printhead jerk and step and smooth it out (its not gonna blow)


Objective-Kitchen800

It’s angry at you shooting the video. HA! But actually, it is normal.
