The noise coming from my controller fan has changed from the normal sound from when I first got it to a louder vibration noise. It doesn’t sound good and might be an issue? Is anyone else experiencing this? Sometimes the noise is there straight away after powering the unit on and sometimes the noise only changes after a print has been going on for a while (2+ hours).
I have noticed this as well…I have noticed the noise when I first turn the machine on but it will go away for me after a few minutes.
On a similar but related note I have noticed my axis stepper motors making more noise lately, has this happened for anyone else? Is there any type of cleaning or lubrication that needs to be done? I have been doing a fair amount of laser engraving on wood, leather, plastic, paper and cork materials…perhaps the small detrius is finding its way to the motors?
Hello all my machine in general is very noisy, but this is my first printer and I don’t know if this grade of noise is inner the normal parameters.
How can know if the noise generated by the machine is between the normal parameters or if more noisy than the normal.
When I use the printer, the combination of the fan of the printer module with the X axis, is too noisy.
Thanks in advance for your comments and ideas!
I’m experiencing the same issue and in my case the noise doesn’t go away.
@Rainie - It seems that there are more people having a similar issue as me. Is it possible for me to get a new controller as you mentioned that the fan cannot be replaced
From what you guys are telling, this seems to be the same problem than those big fans for CPUs had (the fans are quite similar, the only difference is size). I would try to spray a little bit of lubricating oil.
I’ve had this same issue, the fan on the controller makes an odd whining or grinding noise on cold startup, lasts about 20-30 seconds, then tapers off as the fan warms up. I am hesitant to spray anything into the controller, especially as this is a fairly new machine with only about 45-50 hours of printing done on it.
@chadbarba some noise is to be expected, especially as the axes move- perhaps a video of it running (with sound, obviously lol) would help determine if it’s the standard level of noise? or search on youtube, a few Makers have shared videos of their machines running, I realize that volume is relative, but it may give you an idea of what’s normal…
Thank you for your feedback!
I am following this thread and will provide a solution after I have a discussion with the team.
Mine seems to be getting worse, as two days ago it started periodically grinding loud enough to hear from the other end of the house. Noise would continue for 30-45 seconds and stop again for 15-20 minutes. Have since shut it off again, but I’d like to use my snapmaker not have it just sitting on the desk
I’m still having this issue as well, though I have not been doing much with the Snapmaker. Every time I turn it on though, the controller fan is loud for 30 seconds to 1 minute, then gets quieter.
My controller fan is now always noisy. Doesn’t matter how long it’s been running for or if I just switched it on - same annoying loud grinding/buzzing. Pretty sure the bearing is gone and needs to be replaced. Looks like the 25mm fan is permanently mounted to the inside of the controller housing?.. it would of been nice if it was just screwed in so we can all easily replace the fan.
The fans are extremely noisy because they are very small and have to do a lot of rpm do get a decent air flow. You can easily replace them by 24V 40mm fans. They are much more quiet, but for the board you will need a new housing. I will share my results, when I finished a good design.
Another problem are the steppers. Unfortunatelly they are integrated on the board and cannot be replaced by silent tmc step sticks.
I’m having the same issue, when i first go the printer on 6/1 the fan made noise but it was a normal noise. Now its making a grinding noise thats much louder. Rainie this seems to be a common issue, can we get an answer on how you’ll fix this?
Yes, this is a common problem. We have used fans from another brand since January this year, which should not make unbearable noise. If your Snapmaker is still making unbearable noise, please fill in the warranty request at https://www.snapmaker.com/repair. Please provide the following information in your request:
- The color of the label on the fan next to the nozzle. It should be either blue or green.
- A short video to show us where the noise is from and how noisy it is.
Our support team will send you new fans after the request is verified.
Keep having fun!
What spec are the various fans - in case we want to look at alternatives?
Here are the specs:
- The fan next to the nozzle: 25 x 25 x 10 mm, 24 V;
- The fan inside the 3D Printing Module next to the heat sink: 30 x 30 x 10 mm, 24 V.
- The fan inside the controller: 25 x 25 x 10 mm, 24 V;
Here are the videos you can refer to when you replace the fans:
I’ve successfully reduced the noise of the controller fan by printing a new controller case (not on the SM1 since the machine is too small):
Did you by chance finish your design? My fans are driving everyone in my house mad and I am keen to try something to make this noise monster quieter.
The best and easiest way to get rid of the noise imo is to properly install a bigger and quieter fan outside the case, instead of inside since there’s no much room. An adapter can be easily made for this purpose if required, on the Snapmaker itself, without having to replace the whole controller case.
Using an optional fan grill can enhance the look of the installation.
Too bad the fans on the Snapmaker are all working on 24v: that excludes the Noctua fans which are really awesome!
