Hi, everyone,
the F350 is much quieter than the old models. Unfortunately I have a loud noise during the infill. In the video you can hear it when the print head moves from the bottom left to the top right. I print at 50mm / s.
Have you ever had the problem?
Regards
Michael
Always difficult to interpret sound from a video, but my first guess would be resonance of one of the steel strips on one of the linear modules.
If it goes away when you touch the steel strip(s) and it goes away you have identified the source of the sound. You can try tightening it, but normally itās not really a problem (if that is the source)
My first guess was also the steel straps. when I press you / touch it nothing changes. With my old T250 I used to have the problem that the straps were loose, so I tightened them. But the problem was different back then.
When i print with 50mm/s can you hear at the begining from the video the loud noise, at the end from the video i have change the speed to 35mm/s and it is quieter.
@michaelapp did you try touching the dust covers on all of the Linear Modules? From the video, watching the movement and listening to the sound, it seems that it may be originating from either the Y-axis or the Platform. Accessing the covers on the Y-axis could be a little tricky, but you might be able to attach a cotton ball to the end of a screwdriver to reach the touch points.
I think the linear modules of the Y-axis are causing the problems / noises. I touched the dust cover with a cloth, but it didnāt quieter. It sounds as if the noises come from the inside of the linear modules, it doesnāt seem to be due to the covers.
I have now unscrewed the heating plate and tested the movement, because the noise is really annoying.
When i move the plate quickly in 10mm steps, i get the noise. Do you have the same with other F350 or F250 models? I think I have a Monday device, as they say in Germany when there are only problems with one device. My power pack has also smoked. Iām just not happy with what you get for the money.
@michaelapp open a Support ticket and include this video with it. They should be able to either help you fix the issue, or send you replacement parts to fix it. It sounds like something is rattling around, but I donāt know where exactly. There could be something loose inside of the linear modules, or something is loose on the platform. You might want to check everything nearby, is case itās just a loose bolt.
The screws of the linear modules and the platform are tight. I open a support ticket
Hello guys,
I received my F350 and its doing the same strange noise from Y linear modules somehow. They
were even not running smooth when I aligned them while building upā¦ Is there perhaps a fix for
that issue?
Thanks and happy new year to all

Hello everyone,
I am in contact with the support because of the loud scratching noise that you can hear in the video when printing the infill.
Does a 350 Snapmaker owner have the time and desire to print the part to let me know if he has the scratching (from second 18) too?
Regards
Michael

I have the impression that this is one of the metal strips of a linear module that is resonating. It starts when the infill is printing, which happens at a higher speed and in your case causes some vibration that resonates with the metal strip.
If this is the case, it should stop or dampen very much if you put your finger on the strip when it happens. Then you can either not worry about it or try to tighten the strip (search the forum for videos and instructions on how to do this)
edit: nevermind: you were the original poster. thought this was someone new asking again. replied the same before and you said it wasnā4t the case
@michaelapp
with which parameters do you drive in the file!
with what was the gcode generated Snapmaker or Cura !?
do you have the .stl file so that I could slice it myself,
to see with which speed you print.
Have here nen A350T full equipment and would print the file times for you
Hy,
i have generate the gcode with Cura and print the infill with 50mm/s.
Attached can you find the STL File.
Thanks !!!

I upgraded my A350 Correct installation. Correct use. Suddenly a print fault. Recalibrate the print head and hit the bed. Itās all stuck. Two of the shaft stoppers are brokenā¦ The workmanship of the upgraded parts is really worryingā¦ Sad. I have contacted sm for processing. I wish you good luck.
Hello @michaelapp,
yes I found the STL file on Thinkiverse. And my machine isnāt exactly quiet either, but it sounds worse on the phone than when sitting next to it, since I also have the enclosure over it.
But with the thought that something could be wrong I have dismantled the heating plate and the Y-axis times pushed to the stop forward to the door. And lo and behold, the axes are not synchronized with each other.
Now I have done the following:
Now the two Y-axes are aligned to each other.
Next steps are:
I have carried out each step as described in the assembly instructions, but still the Y-axes were not synchronously aligned to each other although with me only minimally but still.
I think it is better to screw the base plate to the Y-axes once you have moved to the home position, because if the base plate is tightened before it comes to tension.
I have the first video still saved on the cell phone and will post it here later, but now first want to make the test with the aligned axes to see how much the noise has changed.
That it does not go completely without is due to the speed and the base plate as a resonance body, possibly you would then have to put cork or felt to drive noiselessly.
So much first from me later more!!!
@michaelapp
Iām doing the calibration of the heating bed and you can already hear that the axes are quieter.
I assume that this is your problem and my description of the solution!
Meld me but later again!
