I have a couple of very annoying issues with Bambu Slicer and the AMS.
Firstly even though when last loaded up it was synched with the AMS subsequently loading Bambu Slicer it will replace some filaments with a completely random filament that I have never used. Eg Bambu Tough yellow will often become ABS.
Secondly and even more annoying the purge settings has on several occasions set the multiplier to zero meaning that no purging is done on colour change, something I only notice when I observe the colour changes are not clean during the print.
