My Printer Broke

The fan in my 3d printer's PSU has been getting noisier and noisier over the last months as its bearings gradually disintegrated. The day before yesterday the damage became too much for it to bear, and the fan just stopped, apart from making the occasional pathetic little scratching noise.

Yesterday I bought a replacement fan, which I thought was the same spec as the original, but of better quality. I had to cut off the plug from the old fan and solder the wires on to the new, as the new fan came entirely plugless.

The new fan was also bulkier than the old. I could get the PSU case closed with it in place, but only just.

I suspect that I created a short circuit in there when everything was crammed back together, because when I switched on, something went
and then everything stopped. My PSU is dead.


I've ordered a new PSU from China, but it will be up to a month before it gets here. So, I'm without a working 3d printer until then. And even then there is no guarantee, as I will have to transfer all the switch and plug cabling over to the new one, and since I am really very ignorant about electronic fiddlery there's a good chance that I'll bollocks it up again.

I guess I'll just have to get started on painting all the bits and pieces I've already printed instead of just steadily adding to the pile of raw plastic things.

  1. Oh. Not fun at all.
    My printer had a small mishap today. Sounded strange suddenly and I looked at it just as something fell off. Turned everything off and found a minute screw.
    Took me a while to go through the Prusa instructions on how to assemble your printer and found what it was. Screwed it back and everything worked as is should.
    That was a relief.
