This is something i caused, no doubt, but these are the events that unfolded yesterday:
-
Print stopped in the middle of an 8hr job. Turns out the Bambu spool came apart (this is my fault - i probably didn’t completely snapped it together when putting the replacement filament on. It printed fine for the first half of the spool).
-
I removed the filament, respooled, but the AMS would not take it. It kept saying to load the filament from the back spool.
-
After a couple attempts, the Bambu app on my laptop crashed. It had a popup that i need to reload the filament, “confirm” or “retry”, but nothing was clickable.
-
I turned off and back on the printer. The filament this time finally loaded fine from the AMS
-
It asked if i wanted to continue the previous print job. I said yes.
-
and then BAM - it somehow forgot that about the previous print job, and crashed the hotend onto the item. The white printhead cover flew off, and the entire print head got bent.
-
Turned the printer off, removed the now damaged print job, restarted the printer, and it said there is an abnormality with the nozzle fan. (understandable, since the nozzle is now damaged).
-
I replaced the hotend (it was the original 0.4) with a brand new 0.6, and did a test print. It threw no errors, but the filament now seems to be too hot (it was very hot to the touch several minutes after the print finished) and the top and sides collapsed.
I submitted a ticket, but they probably were too superficial reading only some parts of my long story, because the response this morning was “sounds like the fan is bad, we will send you a new fan”. I think there is more to it, i just don’t know what. Any ideas?
Screenshots attached. All the errors were before I installed the 0.6 nozzle, no errors after. In the photo of the print, the leftmost item was printed with the 0.4 nozzle before all this saga, and the other two are with the 0.6.
