New hot end fan necessary - hot end fan installation

Postby Allan Sche Sar » Wed Sep 26, 2018 12:09 pm

He there,

a blade from my hot end fan is broken. Can anyone tell me where can I can I buy a new one with shipping to Germany?
And how can I unplug the old one? The cable goes into the back from the hot end and I don't find any screws to follow the cable.

Best regards,


Evan

It's a common off the shelf item that you can easily get within Germany. Use the information on the fan blade housing to get the spec of the fan.

I have the specs see the picture.
@Shelton OKM3D has a delivery slot of 10-20 days. That is too long :(

And I don't know how to get to the plug.

At worst, you can cut the plug and wire from the bad fan, and solder them to the wires for the new fan.

The connectors on a N2 (and probably the Pro2) are the JST P/N: XHP-2 Housing with the JST P/N: SXH-001T-P0.6 crimp

Alex sorry. Yes, I know this. My problem is, that the cable goes into a big hole. Inside I can see nothing. And to follow the cable I must be disassembly the whole print head. I think that is not correct.

just phone to OKM3D - they are really kind and helpful! - maybe shipping can be ready faster than 10-20 days..
or maybe they can offer a different solution!

It goes through the hole and up out to the top where the breakout board is next to the extruder motor. You can just unplug it and pull it through the hole.

Thank you guys.

P.S.: The service from OKM3D was in the past not really nice and fast :S

Sorry I didn't understand the question. Evan is correct, it goes in the bottom and comes out the top where it plugs into the breakout board. I suggest that you tie a string or something to the wires before you pull the old ones through. The block is hollow so it can be difficult to push the wires back through.

Yesterday I installed the MC35101V2-A99 from Sunon. The key features are the same but the fan is a lot of quitter. I love it.
The only problem was, that the cable from the fan was not long enough. So I solder a longer to the fan.
