Hi everyone,
I received my 08max, but unfortunately it is SO INCREDIBLY loud that you can’t work next to it. This is due to the fans for the motherboard and the heating bed control.
For the motherboard, I will use a slow, large fan. The fan for the heating bed control arrived defective, so I want to use a 4-pin PWM fan.
Has anyone already changed anything in the configuration in this regard?
One of the German youtubers, Gerhard (?) I think is his name, did something to quiet his SV08 Max fan (one of them anyway) and posted a youtube about it. He had a pre-production model, though, so I’m not sure if it will be completely on-point with what’s shipping to Kickstarter backers. Maybe worth a look?.
Please do we us know if you’re able to remedy it, and how. Nobody likes noise.
Seems like a recurring problem in a lot of China 3D printers, year after year.
Hello,
i changed the mainboard fan to a noctua with the same specs - and the printer is waaaay quieter now
You probably mean Gergo, from Hungary.
I swapped the SV08 (not Max) motherboard fan for the Noctua equivalent and didn’t change anything else and it’s very quiet with no motherboard overheating.
Try removing the fan and inserting some rubber between the fan and cover plate. I used two layers of VHB tape that I had laying around. It makes a big difference. That large cover plate on the bottom of the printer acts like a big sound amplifier.
I had the same problem – and now I can barely hear the (original) fans.
Solution: I placed the motherboard and the fan above the MOSFET in rubber mounts, thus isolating them from the case. The noise reduction is considerable.
Hi,
Could you post pics of your mod?
Thanks
I replaced the main board fan with a Noctua during assembly, and the fan noise is not an issue at all.
What IS a major issue is the level of noise generated by the stepper motors. They are by far the loudest I’ve ever heard on a 3D printer. Is there any chance there is a drop-in replacement for the stock motors?
Not to knock the good advice on how to reduce noise… but don’t work next to it? 3d printers aren’t actually something you want to be breathing in all day, put it in another room and use the browser based management tool to watch it print in peace, silence, and good air quality.
Regarding stepper motors, a different type/brand won’t be much different, but their noise is based on their speed and load. Running the printer with lower travel speeds and accelerations will have a massive impact in the noise. 700mm/s is extremely impressive, but you can hear it in the next room, halve it and you won’t, and might be surprised how little difference it makes to the actual print times, as the majority of duration is already spent on the slower moves that are unchanged. Often you can more than offset the lowering the peak values by running a fairly quality focused adaptive layer height, or bumping the line widths then reducing infill percentage a small amount.
My fan is not nearly as annoying to me as the filament feeder. That thing will make you want to eat a bullet after and hour. I disable it and replaced it with and Infinity Flow -S1.
I ordered the 80x25mm fan for the fan noise, but it was to thick. since then, I ordered the 80x15mm but have been too lazy to change it, because I have spent the last week trying to get this printer to print correctly.
Good Luck.
That filament feeder is a noisy thing. The fan noise I find acceptable, but the feeder is definitely something I’ll be seeing if I can quieten it down.
