Hello! I was printing a item and at some point machine stopped. When I opened the printer it looked like this:
Could you give me a hint of what has happened / how to fix (maybe, instructions) and if needed spare parts number?
This is an easy one to fix and all one needs is the Allen wrench supplied with the product.
Follow the instructions in the link below. It includes a video and all the part needed to replace the nozzle.
As for how it happened? You tell us. That nozzle took a hard hit. Do you keep the time-lapse camera feed running? If so, even after replacing the nozzle, I would closely review the feed to see exactly what happened. The only scenario that comes to mind is that, at some point, there might have been a model left on the plate by accident. When the printer started up, it could have knocked the model hard. This may have introduced a crack, which could have weakened over time.

That is kind of what bothers me… It was a fresh print with nothing on the plate, because the plate was just swapped from hot plate to the textured PEI plate and some calibration was run on it. Nothing else. The print chunk that you see can see on the photos is literally the piece of item that was in process of printing when this happened.
I saw that print pic, so I think it must have happened a print or 2 before & it finally snapped…JMO
So, i looked throug the box with spare parts, and found the nozzle, but not a complete assembly.
How straightforward is the process of attaching other parts to it for replacement (fan, etc…)?
All of your questions are answerable on either the wiki site or on YouTube. Since you already have the nozzle, all you need to do is swap the fan, the thermistor and silicon sock from the broken nozzle. Here’s a video on that.

Thank you. Just found this video too. As well as the Bambu instructions.
Looks like I managed it )) However, the removed nozzle looks weird:
It is like if it was pushed off the tube that comes from the heatsink.
What that may mean?
There was an issue with nozzles doing this some time back. You may consider contacting BL and seeing if they will replace the broken nozzle. Include all the pics you have shown when you open the ticket.
It sounds like a problem that should be on a list of recall items.
I’m guessing no such single location list exists.
