Are there any plans to turn OFF the long BEEP before printing ?
I sent the start print command so I know the printer is going to be moving.
The Sound OFF in the settings menu does not change the Pre-Print Long Beep.
At night time it is very loud and very long and very annoying.
Loud beep? Mine doesnāt beep. Thereās a little melody that plays before it starts movingā¦ Iām not usually a fan of noises but I find it kinda pleasant and reassuring, not like an obnoxious beep. Iām not sure what youāre hearing, but the start and end sounds are programmed in the machineās start and end g-code (in printerās properties in Studio).
Is it a laser module thing, do you have that?

You can turn off all off the sounds if you prefer, thats how mine is setup.
Coming from the X1C, the sounds of the H2C really bothered me. That was the first thing I turned off in the settings 
What bothers me more are the pointlessly frequent empty runs of the print head before each print, during which it constantly moves back and forth and the filament cutter arms are folded in and out EXTRA LOUDLY each time.
Just out of curiosity. Is the nice melody (yes I like it!) made by some kind of stepper motor motion? Or is there a speaker in the housing?
Doesnāt help much if it would do it less at startup. Some motions are required to go that far back while others require to come forward. Some optimization might be possible though. However, on each nozzle wipe during printing, you will have the same.
Are you connected to a UPS? I experienced this too, and it turned out that my H2C was drawing almost 1500W when heating the bed and chamber at once. That overloaded my 1000W UPS, which started screaming. I enabled ālow power modeā to stop this from happening - it heats slower, but it wonāt kill my circuits haha.
No long beep on my H2C. Plays a few notes at the start and end of a print job, reminiscent of the chimes played on trains in Asia when theyāre pulling in to a stationā¦ Would like a volume control, since itās a lot louder than it has to be, what with my printer about 3 feet away from my left ear. But otherwise unobjectionable.
And yes, pretty sure thereās a speaker in there somewhere and itās not using the steppers to make the tones.
Ha, yeah the startup melody would be a bit loud if right next to meā¦ through a wall/door itās nice!
According to Google AI the start/end sound g-code does vibrate the stepper motors. And apparently the L, M, & N parameters could be the volume. Of course it could be hallucinating.

You can definitely make music with the steppers. Anything that moves fast enough, really. Decades ago, I worked for a company that made HDDs. And every Christmas, weād reprogram a few to play Christmas tunes with the actuator inside that moved the heads around. I fly drones, and the speed controls for the electric motors can be programmed to play a startup tune using the motor coils.
The problem with using a stepper (or actuator or electric motor) to make music is that different frequencies excite different resonances that make tones louder or softer, or that cause other elements in the mechanical structure to buzz/vibrate out of tune.
The tones emitted by the H2C are ācleanā. I could be wrong, since Iām just guessing. But the soundās fidelity sounds too good to me to be coming from a vibrating motor. 
Thank you for this info. Very interesting!
I know, was listening to 8" floppy drives play tunes several decades ago. Wrote firmware for ESCs. I was just pointing out that you may be able to control the volume with the code.

I donāt actually know but drones can play a tune using the BLDC motors which I believe Bambu use in their extruder. So itās a guess they are using that.
Oh it does. I experimented for fun a while back to generate music from a midi file selecting some tracks so it can be played by the printer.
Iiās very rough and unpolished but you can actually experience what you can get from the motors. Just extract the gcode from the zip file, put it on your USB stick and print (you will click print but donāt worry, itās not an actual print, it will just play the music)

The link may not work by just clicking on it, so if not, copy the link in your browser and press enter to download (your browser might say itās not safe to download but it is, itās my work not a dubious download I copied)
Edit: Bambu even provided a guide for the A1mini which works the same on H2x 
Id like to replace the beeps with user custom sound files. Not sure what Iād like it to say when it starts, but Iām sure I could think of something more fun than ābeepāā¦
I donāt think I have a long beep at the start of a print but a melody like tadada tadadi but I will be more careful next time. If itās a beep I donāt think it comes from the motors.
THATS EXACTLY WHAT IT IS!!! Itās so loud that I just figured it was coming from my printer. I have it connected to an APC 1500. Thank you so much for that info. I feel so dumb not paying attention to it, but it sits below my printer so itās hard to tell where its coming form.
I confirm this is coming from the APC during warmup of the build plate. My X1C for a short while exceeds current absorption rate so the APC beeps
I have to agree with this. Itās kinda happy. I like that.
