replacing nozzle fan on N2+

Postby Jab136 » Thu Sep 21, 2017 10:42 am

so, while I was taking my left nozzle off to try to clean it I accidentally broke off one of the blades on that fan and although it still runs and seems to work fine, it isn't ideal and I would like to replace it, are they just regular off the shelf computer cooling fans, and even if they aren't can I use off the shelf cooling fans to replace them?

Standard fan is a 35x10mm 12V fan. Jut about any fan within standard catalogs will work, connector is 2 pin JST-XH series.

Also, read this thread viewtopic.php?f=4&t=903&p=8548&hilit=replacement+fan#p8548

Also, when replacing, attach this sticker (may need to be scaled or adjusted to match the holes). Created by user "Eighty" in the old MakerBot forum years ago https://groups.google.com/d/msg/makerbo ... U7DmkUThgJ

Just saying, this is the most common way to break a fan, people around the world do it all the time so you aren't alone.

You can, unplug the fan on the side of the breakout board or turn off the printer during repair operations.

The safest practice is always to power down when doing mechanical work on any machine.

Curiously, what's the connector part no. and the crimper part no for the terminals?
