Thank you everyone for your replies!
TLDR: No! The current AMS variants do not let you switch between filaments when bypassing the AMS feeding funnel.
Not exactly the same but some alternate options are:
-
Manual per layer pauses to switch filament (difficult and time consuming)
-
use AMS compatible filament like TPU for AMS.
-
break bambu slicer to let you use TPU on the left nozzle (maybe just say it’s PLA with custom settings to match TPU)
