== How To Destroy Your Bambu P1S Hotend ==
[[File:Bambu P1S - hotend nozzle dislocation.webp|thumb|This is catastrophic]]
Bambu Studio reloads all your filament settings when you load a <code>3mf</code> file. What I didn't notice was that it also changes what each slot on your AMS2 is mapped to. So, if your AMS2 had PETG in the A3 slot, you can end up with the AMS2's settings getting overridden by the filament setting in the project file. Now, a smarter more-experienced person would look at all the mappings, re-verify that they are the same, and then send the sliced file to the printer. If there is an excuse it was because I had a few minutes between caring for Astra to do this, but the truth is that I just didn't know this was a thing. I'd printed on one filament, opened a new project file and printed on the 'same' one.
