UM2 Extruder Fan always on

[greg-hodson 0]

My Extruder fan is always on -as long as the switch on the back is on. This makes it the machine quite noisy to the extent that I switch off the main switch between prints. Anyone else find this? I would expect that if this were normal lots of people would be commenting on it.

I only found 1 related thread for the UM original and it's a year old; this seems to suggest that this is not normal.

Could anyone else please share their experience on this?

Thanks,

Greg

The back/third fan is hard wired to power so it will indeed be on as long as the machine is powered on.

It's normal that it's always on. It's not normal that it is noisy. Mine is too quiet to hear more than about a meter away.

Maybe buy another one? Or take off the label and add a drop of oil? Or maybe a blade is damaged and rubbing?

Mine is noisy when parked at initial position. It makes some vibrations on the case if it's a bit away it's quite silent

Thanks all for the responses. I thought the issue would be that the fan is coming on, I had overlooked the obvious, but now that I think about it it may have been quieter when I first got it. That is a better outcome because it means that once fixed the machine will be quieter all round - will investigate getting a new one.

Thanks again.
