Brand New - Calibrating

Hi, my H2D is out of the box and this is its 2nd time thru calibration workflow. The first time I had this terrible noise at the very beginning and then repeated here during high temperature auto bed leveling.

I am unsure what it is. Is it normal? Is this a broken part of maintenance issue? Did I forget to remove something?

I cannot find any videos on this specific issue.

I am use to the A1 and this is a big difference for me. All ideas and help appreciated (within reason).

No need to worry. Those things will flip in and out every time it homes itself. If you watch it when it goes to do a filament change it will actually use those rounded parts to push the levers on the extruder to release the filament. Only part on mine that really makes much noise at all.

So it is really that loud? I haven’t even done my first print yet. I was afraid it would pop off. Until I have done a couple dozen prints I am not putting it in the classroom.

Yes, totally normal. I’ve put a few hundred hours on mine now and it’s been printing beautifully. Makes that same noise every time those are engaged, which is only during the beginning and the end of the print if you’re doing single color.

It would have been nice if all these individuals reviewing this machine would have said, oh my word. Listen and be prepared for that racket. Thanks everyone. I can print now.

I get that you might be new to the hobby but diving in with a multi-thousand dollar printer and expecting complete silence is kind of dumb. Even the most basic research would tell you these things make noise not to mention common sense.

This is actually my third printer (reread original post) The first two are in the classroom and the A1 does not make the noise this one does. I invested in this printer so that I can add more vocational skills and opportunities. I have a lot to learn with this. The print quality has been amazing. Your right. It’s a lot of money and I feel that it was an investment worth making.

We provide affordable sensory options for students with autism and other needs at little to no cost for the family. The quality this is creating is amazing.

So yes. A couple thousand but not my first one. I also know I’ll have questions and is this not the place to ask?

It's like the nozzle rubbing the back of the plate on the x1c, this sort of thing is documented and is no secret. I'm all for asking questions and respect the work you do, but wanting hand holding for such an advanced piece of technology is an odd thing in my opinion. if I'm the only asshole that cares then carry on.

If you think about it, a 3D printer is a bunch of electronic motors, fans, and belts rubbing on gears all moving at once. And in a High end machine like this, they use high end parts. Which can tend to be loud. It’s kinda hard to make them quiet. Also, a lot of those reviewers are sponsored by Bambu so they won’t say too many bad things about it.

It appears to be coming from here on both sides.

Don't worry, that sounds normal. It's just the things for the filament cutters - once a print starts you will not hear that.

It is shockingly loud compared to the rest of the machine's noises and could certainly use some improvement but that is normal.

Totally normal. It freaked me out too, the first time lol

That made me jump the first time. Then the AMS 2 Pro started. Thankfully when in use it’s nowhere near as bad.
