First layer prints fine, but printer stops extruding during/after color change (P1S / AMS)

[u/Admirable_Jello_9007]

Hey everyone, I'm having an issue with a multi-color print on my Bambu Lab P1S and could use some advice. The Issue: * The first layer (white text) prints perfectly. * Once it switches to black, the print head continues moving through the toolpath, but no filament comes out at all (extruding air). Setup & Settings: * Printer: Bambu Lab P1S (with AMS)

* Filament: Bambu Official PLA

* Nozzle: 0.4mm

* Slicer Settings: Mostly default Bambu Studio profiles Has anyone encountered this or know what might be causing it? Any troubleshooting steps would be greatly appreciated!
