Question about bed fan

Post by crazyg0od33 » Sun Aug 14, 2016 2:07 pm

Hey everyone!

So I printed this - http://www.thingiverse.com/thing:443466 - to monitor my prints via octoprint. However, the way the bed fan came set up, like this:

Default Orientation
Makes the bed fan hit the camera and knock it off. Is the fan supposed to be like that (tbh it seems like its pointed to the right of both nozzles when it's in that orientation anyway...) or is it supposed to be like this:

Rotated Bed Fan
Where it's rotated down to actually aim at the nozzles (and also not hit the camera mount?)

Thanks

I don't own a duel setup but according to the instructions it looks like your first picture is the correct setup.

As long as it's point at the nozzles though it shouldn't matter how it's setup though.

Hm thanks. I'll test print quality both ways to see if there is a difference just because the first way (which like you said looks correct from the instructions) didn't seem to point at the nozzles at all.

The first orientation is correct, but i was getting a lot of excess ooze out of the left nozzle with it, so i did a quick rework of the motor fan guard to re-align it.

Ok I like that one!

Compact and pointing at the nozzles. I think I'll print that soon.

Thanks

I also did a fan remount on my dual, with an attempt at a shroud. Combined with my sooper fan, I was able to get very creditable 60 degree overhangs facing away, and 70 degrees facing front.

Yet another fan mod. I changed to a pair of 40mm fans for the filament drives and an 80mm fan for the bed - mainly so I can run it slow to keep the fan noise down. viewtopic.php?f=10&t=4377
