Testing extruder assembly fans.

Post by SmakDaddy »

I have been building the Felix 2.0 in stages over the last few days, and I have hit a snag. With the final stage wiring, I have come to the part where I need to connect the 2 fans on the extruder assembly. In order to tell which fan is which, I used a 9v battery. The fan blowing directly on the back of the extruder spun up fine when the battery was applied, however the fan blowing into the duct doesn't seem to. I have pulled all the wiring back out of the rails to check for breakages, and can't see any, I have pushed the fan in a circle with a screwdriver and id eosnt appear to be hindered by anything. Is this likely to be a faulty fan?

Cheers,

Dave

Thanks, I'll give that a go. I have a few spare ones I picked up at a nearby store as while back

But I'm worried about driving power, air flow, etc. I would much rather use the originals supplied.


UPDATE: I took the fan off to check the solder joints, and found one had a big solder tail which was bent right over and touching the other solder joint (ie, a dead short). A small amount of clipping later, and the fans all good to go :D
