 So weird issues developed with my Vector 3 printer. When I first turn it on it makes a horrible noise It seems to be to do with when it's cold And I think it's the power supply fan Because when I've opened it up and had a look inside that's where the noise comes from I'll disconnect the head so we know that these fans aren't making the noise The unit is currently off and I'll switch it on. I've also found that if I open up this lid And stop the fan It's mounted here in the power supply I've got a little bit of a stick or something This noise stops it suddenly and sometimes that's enough that when the fire is used it fixes it Doesn't sound very good, does it?
