Question about A20M fan placement

Post by rikku » Thu Jan 02, 2020 8:47 pm

Hello,

I'm new to 3D printing. Recently, I had a problem with the hotend so I replaced it. But I don't take care about the 2 fans placements. Since, my printer often pause printing without error message. I just have to select "Resume" to continue but it's a little bit annoying for long prints.
I suspect I mount the 2 fans in a wrong way. Actually, the 2 fans take the air from outside to the hotend.

Could you confirm the direction of the air flow ? (I wonder if left fan take air to the hotend and the right to outside, but not sure).

Sorry for my stupidity -_-!

Thanks for answer.

My question is more about the direction of the air flow of each fans. Is it from inside the hotend to the outside or vice versa ?

I tried to draw my question, see files below :)

What is correct ?

No. 2???

On my A10M it was configuration No.1 from factory (2018/10 model). Warm flow is going to printed model.

So what is right in reallity?
A10M Slic3r profile: here and fresh on github (lot of tips here)
A10 Slic3r profile: here
TIP: tight all screws and wheels (except right side of Z axis) and re-align frame while assembly. And silence it.

I don't think the fans on the sides go to the model. It's the 3rd fan's role, the one with a duck to cold the print. Maybe I'm wrong ?

Hello,
I want to change the fans, in order to get something quieter.
Does someone has good links to quieter fans?

Power supply's Fan :
60*60*15 mm / 12 V / 0,2 A

MotherBoard's Fan
50*50*20 mm / 24V

Best regards,
Christophe
