High Pitch Sound When Printing

Hi All,

This is my first 3D printer and have been enjoying it when it works. Last week I had an issue with the hotend not heating up after only doing 3 prints, but Sovol support did send out a replacement hotend and board which now works thankfully, they were great to deal with.

Into the main issue, since I got this printer I’ve had a loud noise which is a bit irritating and after watching a few videos of other SV06 Ace Plus owners, I noticed that mine makes a lot more noise. I’m not complaining about the fan noise but a higher pitched noise when the print is happening.

I’ve tried moving the bed and I don’t notice a similar sound, and I’ve moved the toolhead across and that noise doesn’t occur either. Only happens when it’s printing.
I’ve tightened all the bolts on the gantry already, which it didn’t make any difference.

It would be greatly appreciated if someone could help determine what could be the cause of this and what can be done to remedy this sound.

I don’t know how else to describe it but it’s a lot more prominent than the constant fan noise.
I can’t post videos as a new person but here’s a link to the video:

I don’t hear a high pitched noise, just the rattling.
Watching a video for a sound is good & bad…
you might see something that can help, but since every phone picks up sound different, that’s the bad.
It sounds pretty normal to me, but someone else might be able to pick something else up I didn’t.

Maybe it is just rattling, I don’t know how to describe it correctly, but it’s definitely noticeable from when listen to it.
You can hear it exaggerated at the 23-24 second mark when it’s making the quick motions if that helps to focus on a certain part

I still don’t hear anything abnormal.
I think your just hearing the noise from the metal wheels along the X-Axis…
Like I posted above, somebody else might hear different.

Sounds like normal stepper motor noise when moving fast.

There are tricks that can quiet them down. Google “Klipper stealthchop”

Stealthchop is a Trimec (TMC) utility. TMC built the motor driver chips on your mainboard.

Stealthchop will make your motors quieter but run hotter and be slightly less accurate.

I’ve never tried enabling it so you’re on your own from here on.

Ah right if it’s normal then I guess nothing to worry about then, just in comparison to other videos I seen of the printer they didn’t have that specific type of noise.

Think I’ll pass on enabling stealthchop, don’t want to cause damage to it already

I did notice while I was printing today that if I held onto the Y axis adjuster it did make the noise a bit more quieter and if I tried tensioning the belt more, it went down a bit but after a couple of minutes it went back to the same sound again. Didn’t want to overtighten the belt and cause more issues so just left it as it was before.

it is possible you have a bad belt roller. The recoding fidelity isn’t good enough to say for sure.

It’s also possessable the cover over the roller is acting as a sounding board and amplifying normal stepper motor vibrations.

Time will tell.

I didn’t hear the squeak in your video…but,
My ACE had a squeak from the Y adjuster.
It was difficult to oil, but i did it…and it did remove the squeak.

EDIT: It was difficult because I oiled it with the belt on.

Did more investigating while I was printing today and yeah it doesn’t seem to be as bad if I just hold onto the plastic, where the Y axis adjuster is, it does dampen the noise quite a bit.

Might look into trying to stuff something in between the plastic and the frame to reduce the vibrations.

The prints I had going today didn’t cause much noise so I will have to update another time to properly compare before and after

I shall give this a try one day as well to see if it makes any difference as well.

Saw another post that had the same issue on reddit but it seemed like all they did was tighten the Y axis and it reduced the noise for them. Didn’t really work for me in my case but just in case someone else is wondering about the noise as well.
