If you got it without the AMS I’m not sure if you get the little spring doo-dad (filament buffer) that meters the filament in with the AMS. It’s actually not a big deal if you didn’t get that because many go for a setup with more than one AMS so you need the 4 to 1 combiner part (AMS hub) instead.
I got my 1st AMS as the combo deal and it did come with the little single filament metering thing but quickly saw I wanted two AMS units so had to buy the 4 to 1 combiner part to replace it.
The second AMS came with all the cabling it needed so your first one should to but verify.
